74HC27; 74HCT27
Triple 3-input NOR gate
Rev. 4 — 5 June 2013
Product data sheet
1. General description
The 74HC27; 74HCT27 is a triple 3-input NOR gate. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
VCC.
2. Features and benefits
Complies with JEDEC standard no. 7A
Input levels:
For 74HC27: CMOS level
For 74HCT27: TTL level
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
