description

The ’AHCT08 devices are quadruple 2-input

positive-AND gates. These devices perform the

Boolean function Y

+ A • BorY + A ) B in

positive logic.

The SN54AHCT08 is characterized for operation

over the full military temperature range of –55

°C

to 125

°C. The SN74AHCT08 is characterized for

operation from –40

°C to 85°C.
