Product details

Quad 2-input NAND gate in 14-SOIC — what it is and where it fits

The Texas Instruments SN74AC00D is a quad 2-input NAND gate from the 74AC family, packaged in a 14-SOIC (3.90 mm width) for surface-mount assembly. It operates from a 2V to 6V supply.

Supply range and temperature — board-level fit

Rated from -40°C to 85°C. Supply range is 2V to 6V. Quiescent current is 2 µA maximum.

Switching speed — timing margin for the bus

The 8 ns propagation delay at 5V, 50 pF is the number to check against your setup-and-hold budget.

Lifecycle and sourcing

The SN74AC00D carries an active lifecycle status and is ROHS3 compliant. No last-time-buy risk for new designs.

Frequently asked questions

Can SN74AC00D replace 74HC00?

Yes, the SN74AC00D is a pin-compatible drop-in for a 74HC00 quad 2-input NAND gate in the same 14-SOIC footprint. The key difference is speed: the 74AC family offers an 8 ns propagation delay at 5V, 50 pF versus roughly 15 ns for a typical 74HC00, giving you extra timing margin. Supply range and output drive are similar, so no board change is needed.

Is SN74AC00D compatible with 5V logic?

Yes, the SN74AC00D is rated for a 2V to 6V supply, so it works directly with 5V CMOS and TTL logic levels. The input logic thresholds (low: 0.9V to 1.65V, high: 2.1V to 3.85V at 5V) are compatible with 5V outputs.

What is the propagation delay of SN74AC00D?

The maximum propagation delay is 8 ns at 5V with a 50 pF load. This is the figure to use for timing closure in your design.
