FK PACKAGE (TOP VIEW) 1B 1A NC VCC 4B In these devices, each circuit functions as a quadruple NOR gate. They perform the Boolean function Y = A • B or Y = A + B in positive logic. However, because of the Schmitt action, the inputs have different input threshold levels for positive- and negative-going signals. 1Y NC 2A NC 2B These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals. 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 4A NC 4Y NC 3B 2Y GND NC 3Y 3A The SN54HC7002 is characterized for operation over the full military temperature range of –55°C to 125°C.
