CD74HC4515E 8-Channel Digital Multiplexer/Demultiplexer by Texas Instruments

The CD74HC4515E is a high-speed CMOS logic 8-channel digital multiplexer/demultiplexer integrated circuit designed and manufactured by Texas Instruments. This versatile component is part of the HC family, which is well-known for its high noise immunity and low power consumption, making it a suitable choice for a wide range of digital applications.

With its 8-channel configuration, the CD74HC4515E offers a convenient way to route one of eight input lines to a single output line, or inversely, one input line to one of eight outputs, depending on the mode of operation. The selection of the desired channel is controlled by three binary selection inputs (A, B, and C), which provide an easy interface for microcontrollers or other digital logic circuits.

The CD74HC4515E operates over a broad voltage range from 2V to 6V, providing compatibility with TTL levels while maintaining CMOS low power dissipation. Its on-chip binary decoding makes it ideal for reducing the number of lines through data multiplexing, which can be particularly beneficial in complex digital systems with limited GPIO availability.

Key features of the CD74HC4515E include:

• 8-Channel multiplexing capability
• High-speed operation, compatible with LSTTL outputs
• Wide operating voltage range (2V to 6V)
• Low power consumption
• High noise immunity characteristic of CMOS devices
• Three binary control inputs for channel selection
• Standardized, symmetrical output characteristics
• 100% tested for quiescent current at 20 V

The device is encapsulated in a 24-pin PDIP (Plastic Dual-In-line Package) which is easy to handle and integrate into a variety of electronic circuits. The CD74HC4515E is commonly used in data multiplexing, signal routing, data acquisition systems, and various forms of digital communication where space and power efficiency are of high importance.

For engineers and designers looking for a reliable and efficient multiplexer/demultiplexer, the CD74HC4515E from Texas Instruments stands as a robust choice, offering both performance and flexibility in a compact package.
