MM74HC32
Quad 2-Input OR Gate
Features
■
Typical propagation delay: 10ns
■
Wide power supply range: 2V–6V
■
Low quiescent current: 20µA maximum (74HC Series)
■
Low input current: 1µA maximum
■
Fanout of 10 LS-TTL loads
General Description
The MM74HC32 OR gates utilize advanced silicon-gate
CMOS technology to achieve operating speeds similar to
LS-TTL gates with the low power consumption of stan-
dard CMOS integrated circuits. All gates have buffered
outputs providing high noise immunity and the ability to
drive 10 LS-TTL loads. The 74HC logic family is func-
tionally as well as pin-out compatible with the standard
74LS logic family. All inputs are protected from damage
due to static discharge by internal 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
(3)
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.
