74HC02; 74HCT02
Quad 2-input NOR gate
Rev. 5 — 26 November 2015
Product data sheet
1. General description
The 74HC02; 74HCT02 is a quad 2-input NOR gate. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
V
CC
.
2. Features and benefits
Input levels:
For 74HC02: CMOS level
For 74HCT02: TTL level
Complies with JEDEC standard no. 7A
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options

5. Pinning information
5.1 Pinning
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
