description
These devices contain four independent 2-input
OR gates. They perform the Boolean functions
Y = A + B or Y = A
•
B in positive logic.
The SN54F32 is characterized for operation over
the full military temperature range of –55°C to
125°C. The SN74F32 is characterized for
operation from 0°C to 70°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 voltage ratings may be exceeded provided the input current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
