74HC4051; 74HCT4051

8-channel analog multiplexer/demultiplexer

Rev. 9 — 26 September 2017 Product data sheet

1 General description

The 74HC4051; 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable

for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features

three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a

common input/output (Z) and a digital enable input (E). When E is HIGH, the switches

are turned off. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of VCC.

2 Features and benefits

•Wide analog input voltage range from -5 V to +5 V

•Complies with JEDEC standard no. 7A

•Low ON resistance:

–80 Ω (typical) at VCC - VEE = 4.5 V

–70 Ω (typical) at VCC - VEE = 6.0 V

–60 Ω (typical) at VCC - VEE = 9.0 V

•Logic level translation: to enable 5 V logic to communicate with ±5 V analog signals

•Typical ‘break before make’ built-in

•ESD protection:

–HBM JESD22-A114F exceeds 2000 V

–MM JESD22-A115-A exceeds 200 V

–CDM JESD22-C101E exceeds 1000 V

•Multiple package options

•Specified from -40 °C to +85 °C and -40 °C to +125 °C

3 Applications

•Analog multiplexing and demultiplexing

•Digital multiplexing and demultiplexing

•Signal gating

[2] - 500 mW

P power dissipation per switch - 100 mW

[1] To avoid drawing VCC current out of terminal Z, when switch current flows into terminals Yn, the voltage drop across the bidirectional switch must not

exceed 0.4 V. If the switch current flows into terminal Z, no VCC current will flow out of terminals Yn, and in this case there is no limit for the voltage drop

across the switch, but the voltages at Yn and Z may not exceed VCC or VEE.

[2] For SO16 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K.

For SSOP16 and TSSOP16 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K.

For DHVQFN16 packages: above 60 °C the value of Ptot derates linearly with 4.5 mW/K.

intended for quick reference only and should not be relied upon to contain

detailed and full information. For detailed and full information see the

relevant full data sheet, which is available on request via the local Nexperia

sales office. In case of any inconsistency or conflict with the short data sheet,

the full data sheet shall prevail.

Product specification — The information and data provided in a Product

data sheet shall define the specification of the product as agreed between

Nexperia and its customer, unless Nexperia and customer have explicitly

agreed otherwise in writing. In no event however, shall an agreement be

valid in which the Nexperia product is deemed to offer functions and qualities

Limited warranty and liability — Information in this document is believed

to be accurate and reliable. However, Nexperia does not give any

representations or warranties, expressed or implied, as to the accuracy

or completeness of such information and shall have no liability for the

consequences of use of such information. Nexperia takes no responsibility

damages are based on tort (including negligence), warranty, breach of

contract or any other legal theory. Notwithstanding any damages that

customer might incur for any reason whatsoever, Nexperia's aggregate and

cumulative liability towards customer for the products described herein shall

be limited in accordance with the Terms and conditions of commercial sale of

Right to make changes — Nexperia reserves the right to make changes

to information published in this document, including without limitation

specifications and product descriptions, at any time and without notice. This

document supersedes and replaces all information supplied prior to the

publication hereof.

Suitability for use — Nexperia products are not designed, authorized or

warranted to be suitable for use in life support, life-critical or safety-critical

systems or equipment, nor in applications where failure or malfunction

of an Nexperia product can reasonably be expected to result in personal

injury, death or severe property or environmental damage. Nexperia and its

suppliers accept no liability for inclusion and/or use of Nexperia products in

such equipment or applications and therefore such inclusion and/or use is at

the customer’s own risk.

Applications — Applications that are described herein for any of these

products are for illustrative purposes only. Nexperia makes no representation

or warranty that such applications will be suitable for the specified use

without further testing or modification. Customers are responsible for the

design and operation of their applications and products using Nexperia

products, and Nexperia accepts no liability for any assistance with

applications or customer product design. It is customer’s sole responsibility

to determine whether the Nexperia product is suitable and fit for the

customer’s applications and products planned, as well as for the planned

application and use of customer’s third party customer(s). Customers should

provide appropriate design and operating safeguards to minimize the risks

associated with their applications and products. Nexperia does not accept

any liability related to any default, damage, costs or problem which is based

on any weakness or default in the customer’s applications or products, or

the application or use by customer’s third party customer(s). Customer is

responsible for doing all necessary testing for the customer’s applications

and products using Nexperia products in order to avoid a default of the

applications and the products or of the application or use by customer’s third

party customer(s). Nexperia does not accept any liability in this respect.

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

Terms and conditions of commercial sale — Nexperia products are

sold subject to the general terms and conditions of commercial sale, as

published at http://www.nexperia.com/profile/terms, unless otherwise agreed

in a valid written individual agreement. In case an individual agreement is

concluded only the terms and conditions of the respective agreement shall

apply. Nexperia hereby expressly objects to applying the customer’s general

terms and conditions with regard to the purchase of Nexperia products by

customer.
