Functional Features

• Decodes a 3-bit binary address to one of eight outputs.
• Demultiplexes the selected output line based on the input address.
• High-speed operation suitable for time-critical applications.
• CMOS logic ensures low power consumption and compatibility with a wide range of devices.

Advantages and Disadvantages

Advantages

• Efficient decoding and demultiplexing of binary information.
• High-speed operation allows for quick response times.
• Low power consumption due to CMOS technology.
• Wide supply voltage range enables flexibility in various applications.

Disadvantages

• Limited to 3-bit input address, restricting the number of output lines.
• Propagation delay may affect timing-sensitive applications.

Working Principles

The CD74HC238M96 is designed to decode a 3-bit binary address and select one of eight output lines based on the input. The enable inputs (E1 and E2) control the operation of the decoder/demultiplexer. When both enable inputs are high, the outputs are disabled. By manipulating the address inputs (A0, A1, and A2), specific output lines can be activated.

Detailed Application Field Plans

The CD74HC238M96 finds applications in various fields, including:

1. Address decoding in microcontrollers and microprocessors.
2. Memory selection in digital systems.
3. Data routing in communication systems.
4. Signal demultiplexing in audio/video equipment.
5. Control signal generation in industrial automation.
