It operates across a 2V to 6V supply range and is rated for -40°C to 125°C. The 14-TSSOP package (4.40 mm width) saves board area compared to SOIC or DIP alternatives. ## What the Schmitt-trigger buys you The Schmitt-trigger inputs accept slow or noisy signals without extra external hysteresis. Input logic low is 1V to 3V, high is 1.5V to 4.2V — the hysteresis window varies with supply. This cleans up signals from mechanical switches, RC oscillators, or long PCB traces that pick up crosstalk. The 2 µA max quiescent current keeps the power budget tight even with all four gates switching. ## Output drive and propagation delay Each output sources or sinks 7.8 mA, enough to drive a standard CMOS load or an LED indicator through a series resistor. Propagation delay is 12 ns typical at 6V with a 50 pF load, which keeps up with most microcontroller bus handshakes and glue-logic paths. For higher drive or faster edges, the 74AC32 (SN74AC32DR) offers 24 mA output and 7.5 ns delay but lacks the Schmitt-trigger inputs and tops out at 85°C.","metaTitle":"SN74HCS32PWR TI OR Gate, Schmitt Trigger, 14-TSSOP","metaDescription":"TI SN74HCS32PWR quad 2-input OR gate with Schmitt-trigger inputs. 2V-6V supply, -40°C to 125°C, 14-TSSOP.
