Product details

The CD74HC32E is a 74HC-series CMOS quad 2-input OR gate in a 14-pin DIP package. It takes a 2V to 6V supply, draws 2 µA quiescent, and can source or sink 5.2 mA per output. 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.

At 6V and 50 pF load the worst-case propagation delay is 15 ns.

No last-time-buy, no NRND flag — this part is still a standard catalog item. The 74HC series has broad second-sourcing from TI, Nexperia, and others, so supply resilience is better than for a niche logic family.

Frequently asked questions

Is SN74HC21N a direct replacement for CD74HC32E?

No — the SN74HC21N is a quad 2-input AND gate, not an OR gate. They share the same 74HC family and 14-DIP footprint, but the logic function is different. For an OR-gate replacement, stay with the CD74HC32E or a pin-compatible 74HC32 from another vendor.
