DESCRIPTION
The 74LX1G05 is a low voltage CMOS SINGLE
INVERTER (OPEN DRAIN) fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
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

regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
