description
The ’AC08 are quadruple 2-input positive-AND
gates. These devices perform the Boolean
function Y = A B or Y = A + B in positive logic.
The SN54AC08 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AC08 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 maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils,
except for the N package, which has a trace length of zero.
