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 is 2V to 6V. Operating temperature is -40°C to 125°C. Quiescent current maxes at 2 µA.
Housed in a 14-SOT-23-THIN. Outputs source or sink 7.8 mA.
12 ns max at 6V with 50 pF load.
ROHS3 compliant.
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.
