74HC32; 74HCT32
Quad 2-input OR gate
Rev. 5 — 4 September 2012
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
Wide supply voltage range from 2.0 V to 6.0 V
Complies with JEDEC standard JESD7A
Symmetrical output impedance
High noise immunity
Low power dissipation
Balanced propagation delays
Input levels:
For 74HC32: CMOS level
For 74HCT32: TTL level
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
