SN74HC161DR Description

Short technical summary and product information.

The SN74HC161DR is a 4-bit synchronous, presettable binary counter manufactured by Texas Instruments. It belongs to the HC technology family and utilizes standard CMOS input and push-pull output types. This counter operates over a wide voltage range of 2V to 6V and offers a typical propagation delay of 14ns. It is designed with internal carry look-ahead for high-speed counting applications and features synchronous operation, eliminating output counting spikes.

 

The SN74HC161DR supports synchronous presetting to any number between 0 and 15. It has an asynchronous clear function. The outputs can drive up to 10 LSTTL loads and exhibit a low input current of 1µA maximum. Power consumption is low, with a maximum Icc of 80µA.

 

This component is available in multiple package types including PDIP, TSSOP, SOP, and SOIC. Its balanced outputs and high-speed capabilities make it suitable for various digital logic designs requiring precise counting and sequencing.
