The SN74HC191NSR from Texas Instruments is a versatile 4-bit synchronous binary counter capable of counting both up and down. This device utilizes HC technology and operates with a standard CMOS input type and push-pull output type. It supports a wide operating voltage range from 2V to 6V and can achieve a count rate of up to 24 MHz.
The counter features synchronous counting operation, ensuring all flip-flops are clocked simultaneously, which eliminates output counting spikes. The direction of the count is controlled by a single down/up count-control line. The device is asynchronously presettable with load control and includes look-ahead circuitry to enhance the speed of cascaded counters.
Designed for surface mount, the SN74HC191NSR comes in a 16-SOIC package. Its features include balanced outputs, high speed with a typical propagation delay of 13 ns, and an output drive capability of ±4mA at 5V. The low power consumption, with a maximum Icc of 80μA, and low input current of 1μA make it suitable for various digital logic applications.
This counter is ideal for applications requiring precise counting and control in digital systems. Its synchronous operation and reversible counting capability provide flexibility in design.
