SNJ54HC191J Description

Short technical summary and product information.

The SNJ54HC191J from Texas Instruments is a 4-bit synchronous, reversible, up/down binary counter. It is designed for applications requiring precise counting operations. The device features synchronous counting, ensuring that all flip-flops are clocked simultaneously, which eliminates output counting spikes.

 

Key electrical characteristics include a wide operating voltage range from 2 V to 6 V, low power consumption with a maximum ICC of 80 µA, and a typical propagation delay of 13 ns. The outputs can drive up to 10 LSTTL loads and provide ±4 mA of output drive at 5 V. Input current is kept low at a maximum of 1 µA.

 

This counter has a single down/up count-control line and features look-ahead circuitry to enhance the speed of cascaded counters. It is fully synchronous in count modes and asynchronously presettable with a load control. The SNJ54HC191J is rated for military applications and operates within a temperature range of -55°C to 125°C.

 

The SNJ54HC191J is available in a CDIP package suitable for through-hole mounting. The standard package quantity is 25 units.
