IMPROVED LATCH-UP IMMUNITY
DESCRIPTION
The 74ACT08 is an advanced high-speed CMOS
QUAD 2-INPUT AND GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS tecnology.
The internal circuit is composed of 2 stages
including buffer output, which enables high noise
immunity and stable output.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
