DESCRIPTION
The 74V1T05 is an advanced high-speed CMOS
SINGLE INVERTER (OPEN DRAIN) fabricated
with sub-micron silicon gate and double-layer
metalwiring C
2
MOStechnology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunityand stableoutput.
PIN CONNECTION AND IEC LOGICSYMBOLS
This device can, with an external pull-up resistor,
be used in wired AND configuration. This device
can also be used as a led driver in any other
applicationrequiring a currentsink.
Power down protection is provided on inputand 0
to 7V can be accepted on inputwith no regard to
the supply voltage. This device can be used to
interface5V to 3V.
