74HC32; 74HCT32
Quad 2-input OR gate
Rev. 6 — 3 December 2015
Product data sheet
1. General description
The 74HC32; 74HCT32 is a quad 2-input OR 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
Complies with JEDEC standard JESD7A
Input levels:
For 74HC32: CMOS level
For 74HCT32: TTL level
Symmetrical output impedance
High noise immunity
Low power dissipation
Balanced propagation delays
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.
