description

These devices contain four independent 2-input 2B 3B NAND gates. They perform the Boolean function 2Y 3A Y = A • B or Y = A + B in positive logic. The

GND 3Y

open-drain outputs require pullup resistors to perform correctly. They may be connected to

SN54HC03 FK PACKAGE

other open-drain outputs to implement active-low

wired-OR or active-high wired-AND functions. The SN54HC03 is characterized for operation over the full military temperature range of –55°C

to 125°C. The SN74HC03 is characterized for 1Y 4A operation from –40°C to 85°C. NC NC 2A 4Y
