It takes a 2V to 6V supply, draws 2 µA quiescent, and can source or sink 5.2 mA per output. The full military temperature range (-55°C to 125°C) makes this the go-to OR gate for avionics, satcom, downhole instrumentation, or any board that lives outside a conditioned room. Four independent gates in one DIP keep the board layout tight — one package handles a four-bit enable mask or a set of alarm-combination logic without a second IC. ## 15 ns propagation delay — timing margin in a mixed-logic bus At 6V and 50 pF load the worst-case propagation delay is 15 ns. ## Active production, no obsolescence risk The CD74HC32E is listed as Active with ROHS3 compliance. No last-time-buy, no NRND flag — this part is still a standard catalog item. For a production BOM that needs a through-hole OR gate in the -55°C to 125°C window, this is a low-risk line item. The 74HC series has broad second-sourcing from TI, Nexperia, and others, so supply resilience is better than for a niche logic family.","metaTitle":"CD74HC32E OR Gate IC, 4-ch 2-in, 74HC, 14-DIP, -55 to 125°C","metaDescription":"CD74HC32E 74HC quad 2-input OR gate in 14-DIP. 2V to 6V supply, 2 µA quiescent, -55°C to 125°C.
