DESCRIPTION
The 74LX1G03 is a low voltage CMOS SINGLE
2-INPUT OPEN DRAIN NAND GATE 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.
The 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 application requiring current sink.
