SN74HCT02M – TEXAS INSTRUMENTS

The SN74HCT02M is a quad 2-input NOR gate fabricated using Texas Instruments’ high-speed silicon-gate CMOS technology. This device operates from a 2V to 6V supply voltage range, exhibiting CMOS logic levels with speeds comparable to low-power Schottky TTL (LSTTL) circuits. The ‘HCT’ designation signifies compatibility with TTL voltage levels, allowing direct interfacing with 5V TTL logic. The SN74HCT02M features low power consumption, with a typical quiescent current in the microampere range. Propagation delay times are typically in the order of nanoseconds, dependent on supply voltage and load capacitance. The ‘M’ suffix denotes a surface-mount SOIC package. The device provides standard NOR gate functionality, where the output is low only when both inputs are high; otherwise, the output is high.
