MC74HC03A
Quad 2-Input NAND Gate
with Open-Drain Outputs
High−Performance Silicon−Gate CMOS
The MC74HC03A is identical in pinout to the LS03. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC03A NAND gate has, as its outputs, a high−performance MOS N−Channel transistor. This NAND gate can, therefore, with a suitable pullup resistor, be used in wired−AND applications. Having the output characteristic curves given in this data sheet, this device can be used as an LED driver or in any other application that only requires a sinking current.
