DESCRIPTION
The 74V1T05 is an advanc ed high-speed CM OS
SINGLE 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 no ise
immunity and stable output.
Power down protection is provided on inpu t an d 0
to 7V can be acce pted on inp ut with no rega rd to
the supply voltage. This device can be used to
interface 5V to 3V.
