Product Description

The CD74HC4520E consists of two identical, internally synchronous 4-stage counters. The counter stages are D-type flip-flops, and the counter can be cleared by a high level on the RESET line. Counting is enabled by a high level on the CLOCK line, and the counters advance on the falling edge of the clock. A high level on the ENABLE line holds the counter in its current state.

The device features a wide operating voltage range, from 2V to 6V, and it can interface with standard CMOS outputs as well as LSTTL/MSI. With a typical propagation delay of only 145ns at a supply voltage of 6V, the CD74HC4520E is suitable for high-speed operation.

Its robust design allows it to operate in extreme temperature conditions ranging from -55°C to 125°C, making it an ideal choice for industrial and automotive applications. The CD74HC4520E is a reliable and versatile component for designers looking to implement counting functions in their digital systems.

Overall, the CD74HC4520E from Texas Instruments is a testament to the company's commitment to providing high-quality, reliable integrated circuits for a broad range of electronic applications.
