Working Principles

The SN74F253DR is designed to perform logic multiplexing and demultiplexing operations. It consists of two 4-input multiplexers and two 1-of-4 decoders. The select inputs (S0 and S1) determine which input is selected for each multiplexer. The selected input is then routed to the corresponding output line.

Detailed Application Field Plans

The SN74F253DR can be used in various applications, including:

1. Data Multiplexing: Selecting and routing specific data inputs to a common output line.
2. Address Decoding: Decoding address inputs to enable the selection of specific memory locations.
3. Signal Routing: Directing different signals to specific destinations based on control inputs.
