DESCRIPTION
The 74V2G70 is an advanced high-speed CMOS
TRIPLE NOT INVERTED BUFFERfabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
The internal circuit is composed of 3 st ages
including buffer output, w hich provide high noise
immunity and stable output.

Power down protection is provided on all inputs
and outpu ts and 0 t o 7V can be accepted on
inputs with no regard to th e s upply voltage.
This device can be used to interface 5V to 3V
systems and it is ideal for portable applications
like personal digital assistant, camcorder and all
battery-powered equipment.
All inputs and outputs are equipped with
protection circuits aga inst st atic discharge, giving
them ESD immunity and transient excess voltage.
