description
The ’AHCT32 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 SN54AHCT32 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AHCT32 is characterized for
operation from –40°C to 85°C.

‡
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
