Product details

Quad 2-input AND gate in 14-SOIC — what you get

The Texas Instruments SN74AC08DR packs four independent 2-input AND gates into a single 14-SOIC package, each output capable of sourcing or sinking 24 mA. It runs from a 2V to 6V supply, making it a straightforward choice for 3.3V or 5V logic rails in industrial control, sensor interface, or general-purpose glue logic where you need a clean AND function without reaching for a CPLD.

With a maximum propagation delay of 7.5 ns at 5V into 50 pF, this gate keeps up with most 50–100 MHz bus signals. The 74AC family balances speed and quiescent current (2 µA max) — fast enough for address decoding or clock gating without the shoot-through current of older 74F parts.

The 2V to 6V supply range means it can sit on a 3.3V rail with a 74LVC neighbor or on a 5V rail with legacy 74HC logic — just watch the input thresholds: low is 0.9V to 1.65V, high is 2.1V to 3.85V, so a 3.3V CMOS drive lands solidly in the valid region.

Frequently asked questions

How does SN74AC08DR compare to 74HC08?

The 74AC08 is faster than the 74HC08 at the same supply voltage — the 74AC family typically offers lower propagation delay for a given Vcc. The trade-off is slightly higher dynamic power. If your design already runs on 5V and timing margin is tight, the 74AC08 is the better fit. For 3.3V-only systems, the 74LVC08 variant (SN74LVC08ADR) offers lower voltage operation down to 1.65V and a faster 3.9 ns delay at 3.3V.
