Product details

Quad 2-input AND gate in 14-SOIC

The SN74AS08D is a Texas Instruments 74AS-series quad 2-input AND gate in a 14-SOIC surface-mount package. It packs four independent AND gates, each with two inputs, into the standard SOIC-14 footprint.

5.5 ns propagation delay at 5 V

Maximum propagation delay is 5.5 ns at 5 V supply into a 50 pF load — this is the AS (Advanced Schottky) speed advantage over the 74LS or 74HC families. The 2 mA output high / 20 mA output low drive means it can fan out to multiple LSTTL loads without a buffer.

Frequently asked questions

What is the propagation delay of SN74AS08D?

Maximum propagation delay is 5.5 ns at 5 V supply into a 50 pF load, which is the key speed spec for timing closure in 5 V logic designs.
