description
The ’AHC32 devices are quadruple 2-input
positive-OR gates. These devices perform the
Boolean function Y+A • B or Y+A)B in
positive logic.
The SN54AHC32 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AHC32 is characterized for
operation from –40°C to 85°C.
