Product details

Quad 2-input NAND gate in the 74HCT family – what it is and where it fits

The Texas Instruments SN74HCT00DT is a quad 2-input NAND gate from the 74HCT logic family. Input thresholds are low 0.8 V and high 2 V. Rated for the industrial temperature range of –40 to 85 °C, this gate suits factory automation panels, motor-drive control logic, and outdoor telecom equipment where ambient temperatures fluctuate. The 14-SOIC package (3.90 mm body width) fits a standard SOIC-14 land pattern and is specified for surface-mount assembly.

18 ns propagation delay – timing margin for 5 V buses

The maximum propagation delay is 18 ns at 5.5 V with a 50 pF load.

Active lifecycle – no obsolescence risk for production runs

The SN74HCT00DT carries an Active product status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. This part can be specified into new designs without worrying about a near-term discontinuation.

Frequently asked questions

Is SN74HCT00DT obsolete or end-of-life?

No. The SN74HCT00DT has an Active product status per Texas Instruments. It can be specified into new production without near-term obsolescence risk.

What is the maximum propagation delay of SN74HCT00DT?

The maximum propagation delay is 18 ns at 5.5 V supply with a 50 pF load. At lower supply voltages the delay increases; the datasheet curve provides the derating.

Is SN74HCT00DT a drop-in replacement for SN74HCT00N?

Functionally yes – both are quad 2-input NAND gates with the same 74HCT thresholds and 4 mA output drive. The difference is the package: SN74HCT00DT is a surface-mount 14-SOIC, while SN74HCT00N is a through-hole PDIP. They are not footprint-compatible without a board change.

Is SN74HCT00DT RoHS compliant?

Yes. The SN74HCT00DT is ROHS3 compliant, meaning it meets the EU RoHS directive with no restricted substances above the threshold limits.
