MM74HC02
Quad 2-Input NOR Gate
General Description
The MM74HC02 NOR gates utilize advanced silicon-gate
CMOS technology to achieve operating speeds similar to
LS-TTL gates with the low power consumption of standard
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 functionally as well
as pin-out compatible with the standard 74LS logic family.
All inputs are protected from damage due to static dis-
charge by internal diode clamps to V
CC
and ground.

Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.

DC Electrical Characteristics
(Note 4)
Note 4: 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.
