74HC2G08; 74HCT2G08
Dual 2-input AND gate
Rev. 5 — 8 October 2013
Product data sheet
1. General description
The 74HC2G08; 74HCT2G08 is a dual 2-input AND 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
Input levels:
For 74HC2G08: CMOS level
For 74HCT2G08: TTL level
Symmetrical output impedance
High noise immunity
Low power dissipation
Balanced propagation delays
Multiple package options
ESD protection:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
