General Description
The MM74HC14 utilizes advanced silicon-gate CMOS
technology to achieve the low power dissipation and
high noise immunity of standard CMOS, as well as the
capability to drive 10 LS-TTL loads.
The 74HC logic family is functionally and pinout compat-
ible with the standard 74LS logic family. All inputs are
protected from damage due to static discharge by inter-
nal diode clamps to V
CC
and ground.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.

Absolute Maximum Ratings
(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
Notes:
1. Unless otherwise specified all voltages are referenced to ground.
2. Power Dissipation temperature derating — plastic “N” package: –12mW/°C from 65°C to 85°C.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.

DC Electrical Characteristics

Note:
3. For a power supply of 5V ±10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V
values should be used when designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
=
5.5V and 4.5V
respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage current (I
IN
, I
CC
, and I
OZ
) occur for CMOS at
the higher voltage and so the 6.0V values should be used.
