The SN74LS191DR is a synchronous, reversible 4-bit binary up/down counter from Texas Instruments. It operates within a voltage range of 4.75V to 5.25V and features LS technology for high-speed performance with typical propagation delays between 10-50ns. This counter is designed for surface mount applications and comes in a 16-SOIC package.
Key features include single down/up count control, count enable control, ripple clock output for cascading, and asynchronous presettable load control. The device offers parallel outputs and is cascadable for n-bit applications. Its synchronous operation eliminates output counting spikes commonly found in ripple counters. The operating temperature range is from 0°C to 70°C.
This counter is suitable for digital logic designs requiring precise counting and control. Its ability to count both up and down, along with its synchronous nature and cascadability, makes it versatile for various digital system implementations.
