It integrates four independent NOR gates, each with two inputs, on a single IC. Operating from a 4.5V to 5.5V supply, it delivers 4mA source and sink output current with a typical quiescent draw of just 2 µA — suited for 5V TTL-compatible logic systems where low standby power matters. The 18ns maximum propagation delay at 5.5V and 50pF load sets the timing budget for the signal path — a 55 MHz toggle ceiling in a 5V rail, though real throughput depends on the fan-out and trace capacitance. ## Supply voltage and temperature grade The input logic thresholds are 0.8V low and 2V high, directly compatible with 5V TTL levels — no external level translation needed when driving from a 5V microcontroller or another 74HCT output. ## Package and PCB integration The 14-TSSOP body (4.40mm wide, 0.65mm pin pitch) is a common footprint shared with many 14-pin logic ICs. The supplier device package is 14-TSSOP, and the mounting is surface-mount.","metaTitle":"SN74HCT02PWT Texas Instruments 74HCT Quad 2-Input NOR Gate","metaDescription":"Texas Instruments SN74HCT02PWT quad 2-input NOR gate, 74HCT series, 4.5V-5.5V supply, 2 µA quiescent, 18ns prop delay.
