Texas Instruments CD74HC191EG4 is a high-speed CMOS binary counter from the 74HC series. This synchronous, 4-bit counter features both up and down counting capabilities, controlled by a direction input. It operates on a voltage supply range of 2V to 6V with a maximum count rate of 35 MHz. The counter is triggered by a positive edge on the clock input and includes an asynchronous reset function. Packaged in a 16-pin PDIP (0.300", 7.62mm), this component is suitable for through-hole mounting. The CD74HC191EG4 finds application in digital systems requiring precise counting and sequencing operations, including industrial control, data acquisition, and communication infrastructure. Its wide operating temperature range of -55°C to 125°C ensures reliable performance in diverse environmental conditions.
