What are the key features?

Wide 2V to 6V operating voltage, 15ns propagation delay, and low power consumption.

What is the package type?

It is housed in a 14-pin SOIC surface-mount package.

What should engineers review?

Check the timing requirements (setup/hold times) and ensure unused inputs are tied to VCC or GND.

What should sourcing teams check before buying SN74HC74DR?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: low; readiness: easy.

What is the pinout of SN74HC74DR?

Use the SN74HC74DR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SN74HC74DR pinout to locate pins, power rails, and interface signals before layout.
