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 is 2V to 6V. Quiescent current is 2 µA maximum.
The 8 ns propagation delay at 5V, 50 pF is the number to check against your setup-and-hold budget.
No last-time-buy risk for new designs.
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.
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.
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.
