The 74HC191 from Texas Instruments is a high-speed synchronous, reversible, 4-bit binary up/down counter. It utilizes advanced silicon-gate CMOS technology, offering high noise immunity and low power consumption comparable to low-power Schottky TTL speeds.
Key electrical specifications include an operating voltage range of 2V to 6V, with a typical operating voltage of 5V. The counter operates at a frequency of up to 13MHz and has a propagation delay of 60ns. It features positive edge clock triggering and a maximum supply current of 50mA.
This counter is designed for synchronous operation, meaning all flip-flops are clocked simultaneously, ensuring simultaneous output changes and eliminating counting spikes. It is available in a surface-mount SOP package.
The 74HC191 is suitable for various digital logic applications requiring precise counting and control. Its wide operating temperature range of -40°C to 125°C makes it adaptable to diverse environmental conditions.
