DM54LS153W/883

Overview

The DM54LS153W/883 is a dual 4-input multiplexer belonging to the LS Series of logic integrated circuits. It features two independent multiplexing functions, each selecting one of four data inputs based on two address lines. The device utilizes TTL technology and is housed in a ceramic flatpack package (CDFP16). Designed for military-grade reliability under MIL-STD-883 standards, it operates within an extended temperature range of -55 °C to 125 °C with a nominal 5 V supply voltage.

Feature Summary

• Dual independent 4-to-1 multiplexing channels
• Ceramic flatpack construction for rugged environments
• Compliant with MIL-STD-883 qualification standards

Applications

• Military avionics signal routing
• Spacecraft data bus switching
• High-reliability industrial control systems

Procurement Notes

Verify that the component carries the specific /883 suffix indicating compliance with MIL-STD-883 testing requirements. Confirm the manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments. Ensure the ceramic flatpack package matches the required footprint for your PCB design. Check for any lot traceability documentation required for defense or aerospace procurement contracts.

Selection Notes

Select this part when dual-channel multiplexing is required in harsh environments where standard plastic packages may fail. The LS series offers a balance of speed and power consumption suitable for battery-operated or thermally constrained military applications. Compare against the DM54LS151 if single-channel operation suffices, or the DM54LS157 if quad 2-input selection is needed instead.

Part Context

This component is part of the DM54LS family, which denotes military-grade Low-power Schottky TTL logic. The 'DM' prefix typically indicates a military grade device, while 'LS' specifies the logic family characteristics. The '/883' suffix confirms adherence to the MIL-STD-883 test method for microelectronics, distinguishing it from commercial variants like the DM74LS153.

FAQ
