It runs on a 2V to 6V supply. The 14-DIP through-hole package fits prototyping boards, legacy backplanes, and MRO replacements where the board is already laid out for DIP sockets.
Quiescent current is 2 µA maximum across the full supply range. The 5.2 mA per output (sink or source) is typical 74HC drive — enough for a standard TTL load or a low-current LED indicator, but not for a relay coil directly.
Maximum quiescent current is 2 µA across the full supply range, making it suitable for power-sensitive designs.
The SN74HC7032N includes Schmitt-trigger inputs; the standard SN74HC32N does not. If your application needs noise immunity on slow or noisy edges, the 7032 is the right choice. If the input signals are already clean, the SN74HC32N is functionally equivalent for the OR logic function.
