DESCRIPTION
The 74V2T05 is an advanced high-speed CMOS
TRIPLE INVERTER (OPEN DRAIN)
fabricated
with sub-micron silicon gate and double-layer
metal wiring C
2
MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protection is provided on input and 0
to 7V can be accepted on input with no regard to
the supply voltage. This device can be used to
interface 5V to 3V.
