CD74HCT4520E Dual Binary Counter from Texas Instruments

The CD74HCT4520E is a high-performance CMOS logic dual binary counter integrated circuit brought to you by Texas Instruments, a leader in semiconductor design and manufacturing. This device is part of the 74HCT series, known for its compatibility with standard TTL integrated circuits while offering the benefits of high-speed CMOS technology.

Constructed with silicon gate CMOS fabrication, the CD74HCT4520E ensures low power consumption and provides a reliable solution for a wide range of counting applications. The dual binary counter consists of two identical, internally synchronous 4-stage counters. The counter advances on the falling edge (negative transition) of the input clock signal, which is a common requirement for synchronized operations in digital systems.

Key Features:

• Logic Type: Dual Binary Counter
• Counting Sequence: Up
• Operating Temperature Range: -55°C to 125°C, making it suitable for industrial applications.
• Number of Pins: 16-pin package, which is ideal for space-constrained applications.
• Supply Voltage: 4.5V to 5.5V, which aligns with typical digital logic level voltages.
• High-Speed Performance: Compatible with TTL levels while offering the speed of CMOS technology.
• Output Current: High current outputs that can drive multiple loads simultaneously.

The CD74HCT4520E is designed with features that ensure minimal power consumption during operation. It includes an asynchronous master-reset input (MR) which, when taken high, resets the counter to its zero state. Each counter also has a separate clock input (CP) to initiate counting and a carry out (CO) that provides a high-level output pulse for every complete cycle of the counter's operation, which can be used for cascading counters in multi-stage configurations.

Whether you're designing a digital clock, an event counter, or a frequency divider, the CD74HCT4520E provides a reliable and efficient solution. Its robust design and straightforward operation make it an excellent choice for both prototyping and full-scale production in various electronic applications.
