TI SN74HC132DR

The SNx4HC132 device functions as a NAND gate, but because of the Schmitt action, it has different input threshold levels for positive and negative going signals. The SNx4HC132 devices perform the Boolean function Y = A(overline)·B(overline) or Y = A(overline) + B(overline) 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 SNx4HC132 is a quadruple 2-input positive-NAND gate with low drive that produces slow rise and fall times. This reduces ringing on the output signal. Each circuit functions as a NAND gate, but because of the Schmitt action, it has different input threshold levels for positive- and negative-going signals. These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
