The Texas Instruments SN74LS161ADR is a synchronous, presettable 4-bit binary counter designed for high-speed counting applications. It utilizes LS technology with bipolar inputs and push-pull outputs.
This counter features internal carry look-ahead for fast counting and a carry output for n-bit cascading. It operates synchronously, meaning all flip-flops are clocked simultaneously, eliminating output counting spikes common in asynchronous counters. The buffered clock input triggers on the rising edge. The device is fully programmable, allowing outputs to be preset to any level synchronously.
Packaged in a 16-SOIC (0.154", 3.90mm Width) format, the SN74LS161ADR is designed for surface mounting. It operates within a voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C. Its count rate is up to 25 MHz.
Key specifications include its 4-bit binary count logic, synchronous timing, and asynchronous reset capability. The high-speed feature with a propagation delay between 10ns and 50ns makes it suitable for various digital logic designs.
