Technical details

Quad 2-input AND gate in 14-SOIC

The Texas Instruments SN74AS08DR is a quad 2-input AND gate from the 74AS family, packaged in a 14-SOIC (0.154", 3.90 mm width) for surface-mount assembly. It operates from a 4.5 V to 5.5 V supply and is rated for the commercial temperature range of 0°C to 70°C, making it a drop-in for standard 5 V TTL logic boards in office equipment, appliances, and indoor industrial controls. Four independent AND gates per package, each with two inputs, give you glue logic for address decoding, strobe gating, or enable generation without wasting board space on multiple DIP packages.

Max propagation delay is 5.5 ns at 5 V and 50 pF load. Output drive is 2 mA source, 20 mA sink.

The SN74AS08DR is listed as Active (current lifecycle stage) and ROHS3 compliant. The 74AS series has broad second-sourcing; the SN74F00DR (quad 2-input NAND) is a functional alternative if your logic polarity flips, but the AND function is fixed here.
