Working Principles

The CD74AC238M96 is a 3-to-8 line decoder/demultiplexer integrated circuit. It operates by taking a 3-bit binary input and converting it into one of eight possible output combinations. The enable inputs (E1 and E2) control the operation of the decoder/demultiplexer. When both enable inputs are high, the device is enabled, and the selected output is determined by the binary input. When either or both enable inputs are low, all outputs are forced to a high impedance state.

Detailed Application Field Plans

The CD74AC238M96 can be used in various applications, including:

1. Address Decoding: Used in microcontrollers and memory systems to decode address signals.
2. Data Demultiplexing: Used to route data from a single source to multiple destinations.
3. Signal Routing: Used in communication systems to select specific channels or routes.
4. Control Systems: Used in automation and robotics to decode control signals.
