SN54HCT02, SN74HCT02 quad 2-input positive-NOR gates, operate over a voltage range of 4.5 V to 5.5 V, output can drive up to 10 LSTTL loads, low power consumption of 20-µA Max ICC, typical tpd = 10 ns, ±4-mA output drive at 5 V, low input current of 1 µA Max, inputs are TTL-voltage compatible.
The SN54HCT02 and SN74HCT02 are quadruple 2‑input positive‑NOR gates that implement the Boolean function Y = A·B in positive logic. They are TTL‑compatible, operate from a 4.5 V to 5.5 V supply, and can drive up to ten LSTTL loads.
The datasheet lists absolute‑maximum ratings, recommended operating conditions, electrical characteristics such as propagation delay (typical 10 ns), input‑high voltage (2 V), input‑low voltage (0.8 V), and output voltage levels. It also provides ordering information, package options (PDIP, SOP, SSOP, TSSOP, etc.), and mechanical drawings for each package type.
