SN74LS161ANSR Description

Short technical summary and product information.

The SN74LS161ANSR is a synchronous, presettable 4-bit binary counter from Texas Instruments. It features internal carry look-ahead for high-speed counting designs and synchronous operation, eliminating output counting spikes. The counter has a buffered clock input that triggers on the rising edge and is fully programmable, allowing outputs to be preset to any level synchronously.

 

This component operates within a voltage range of 4.75 V to 5.25 V and has an operating temperature range of 0°C to 70°C. It utilizes LS technology with bipolar inputs and push-pull outputs. The device is available in a 16-SOIC package, suitable for surface mounting.

 

Key features include synchronous counting, a carry output for n-bit cascading, and a direct clear function. The diode-clamped inputs ensure reliable operation. This counter is ideal for digital logic designs requiring precise counting and programmability.
