description
The 'ACT32 are quadruple 2-input positive-OR gates. The devices perform the Boolean function Y = A + B or Y = A * B in positive logic. The SN54ACT32 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ACT32 is characterized for operation from -40C to 85C.

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 maximum package power dissipation is calculated using a junction temperature of 150C and a board trace length of 750 mils, except for the N package, which has a trace length of zero.
