The DM54153J/883C is a dual 4-to-1 line data selector/multiplexer manufactured by National Semiconductor (now Texas Instruments). This device selects one of four data sources from each of the two independent channels, based on the binary address applied to the select inputs. The selected data is then routed to the output. The /883C designation indicates compliance with military-grade specifications for enhanced reliability and performance in harsh environments.

Applications

• Data Routing: Directing data from one of several sources to a single destination.
• Digital Multiplexing: Combining multiple data streams onto a single line.
• Address Decoding: Selecting memory locations or peripheral devices based on an address.
• Logic Function Implementation: Implementing various combinational logic functions.
• Military and Aerospace Systems: High-reliability applications requiring guaranteed performance over a wide temperature range.

Features

• Dual 4-to-1 Multiplexer: Contains two independent 4-input to 1-output multiplexers.
