SN74HC161DR Description

Short technical summary and product information.

The SN74HC161DR is a 4-bit synchronous, presettable binary counter manufactured by Texas Instruments. It is designed for high-speed counting applications, featuring internal carry look-ahead logic. The counter operates synchronously, meaning all flip-flops are clocked simultaneously, eliminating output counting spikes.

 

Key electrical characteristics include a wide operating voltage range from 2V to 6V, a maximum power consumption of 80μA, and a typical propagation delay of 14ns. The outputs can drive up to 10 LSTTL loads, and the device has a low input current of 1μA maximum. The counter has an asynchronous clear function and synchronous preset capability.

 

This component is housed in a 16-SOIC package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C. The SN74HC161DR is designed for applications requiring precise and fast counting operations where synchronous behavior is critical.
