QUADRUPLE POSITIVE-NAND GATES WITH SCHMITT-TRIGGER INPUTS

Each circuit functions as a NAND Gate SN54HC132 SN74HC132 , but because of the Schmitt action, it has different input threshold levels for positive- and negative-going signals. The HC132 perform the Boolean function Y = A B or Y = A + B in positive Logic These circuits are temperature compensated and CAN be triggered from the slowest of input ramps and still give clean jitter-free output signals. The SN54HC132 is characterized for operation over the full military temperature range of 55C to 125C. The SN74HC132 is characterized for operation from 40C to 85C. By Texas Instruments
