What are the key specifications of the 74HC02?

It operates from 2.0 V to 6.0 V, features a propagation delay of approximately 9 ns (at 4.5 V), and is specified for temperatures up to +125 °C.

What should engineers review before using the 74HC02?

Engineers should verify the input logic levels. The 74HC02 uses CMOS levels, while the 74HCT02 variant is designed for TTL-compatible input levels.

What is the pinout of 74HC02D,653?

Use the 74HC02D,653 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about 74HC02D,653 pinout to locate pins, power rails, and interface signals before layout.
