Quad NAND gate with Schmitt trigger — where the hysteresis matters
The CD74HC132M96 is a Texas Instruments 74HC-series quad 2-input NAND gate with Schmitt trigger inputs in a 14-SOIC surface-mount package. The Schmitt trigger hysteresis on each input cleans up slow edges or noisy signals, making this part a standard choice for debouncing switch contacts, conditioning sensor outputs, or squaring up oscillator waveforms in mixed-voltage boards. Supply range spans 2V to 6V, so the same part can sit on a 3.3V microcontroller rail or a 5V industrial bus without a level translator. Outputs source and sink 5.2mA each, enough to drive a standard CMOS load or a low-current LED directly. Quiescent current maxes at 2 µA across temperature, which keeps the standby budget negligible in battery-powered or always-on subsystems.
No special screening needed for the temperature grade — the standard part already covers it. Propagation delay is 21ns max at 6V with a 50pF load, which is typical for the 74HC family at this supply. At 2V the delay will be higher, but the Schmitt inputs keep the output transition clean even with a slowly ramping input.
