DM74LS161AN Description

Short technical summary and product information.

The DM74LS161AN from ON Semiconductor is a synchronous, presettable 4-bit binary counter designed for high-speed counting applications. It features an internal carry look-ahead for cascading counters without additional gating. The counter operates on a positive edge of the clock input and has an asynchronous reset function.

 

Key electrical characteristics include an operating voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to 70°C. The device is packaged in a 16-DIP format, suitable for through-hole mounting.

 

This counter is fully programmable, allowing outputs to be preset to any level synchronously with the clock pulse. The asynchronous clear function ensures all flip-flop outputs are set LOW regardless of other input conditions. The synchronous operation eliminates output counting spikes associated with asynchronous counters.
