What are the key specifications?

It operates from 2V to 6V, supports up to 29 MHz clock frequency, and features a typical propagation delay of 14 ns.

What should engineers review before using this part?

Review the RCO glitch behavior when cascading multiple devices, as it may limit the maximum clock frequency.

Is this part suitable for high-speed applications?

Yes, its internal look-ahead carry and synchronous operation make it well-suited for high-speed digital counting.

What is the pinout of SN74HC161DR?

Use the SN74HC161DR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SN74HC161DR pinout to locate pins, power rails, and interface signals before layout.
