Product details

Quad OR gate with Schmitt-trigger inputs — what that buys you

The Texas Instruments SN74HCS32DYYR is a quad 2-input OR gate from the 74HCS series. Schmitt-trigger hysteresis on every input (1V to 3V low threshold, 1.5V to 4.2V high threshold) prevents oscillation on slow or noisy signals.

Supply range and temperature grade — BOM fit

Supply range is 2V to 6V. Operating temperature is -40°C to 125°C. Quiescent current maxes at 2 µA.

Package and footprint

Housed in a 14-SOT-23-THIN. Outputs source or sink 7.8 mA.

Propagation delay — timing budget note

12 ns max at 6V with 50 pF load.

Lifecycle and sourcing

ROHS3 compliant. No LTB risk for new designs.

Frequently asked questions

Can SN74HCS32DYYR replace 74HC32?

Yes, it is a drop-in functional replacement for a standard 74HC32 quad OR gate, with the added benefit of Schmitt-trigger inputs on all pins. Pinout and logic function are identical; the hysteresis improves noise immunity without any board change.
