DESCRIPTION

The 74LX1G 05 is a low voltage CMO S SINGLE
INVERTER (OPEN DRAIN) fabricated with
sub-micron silicon gate and double-layer metal
wiring C

MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high no ise
immunity and stable output.
This device can also be used as a led driver in any
other application requiring current sink.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
