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.","metaTitle":"SN74HCT00DT – TI 74HCT Quad 2-Input NAND Gate, 18 ns","metaDescription":"SN74HCT00DT from TI: 74HCT quad NAND gate, 4.5–5.5 V supply, 18 ns propagation delay, –40 to 85 °C, 14-SOIC.
