54F153DM-MLS

Overview

The 54F153DM-MLS is a dual 4-line to 1-line data selector/multiplexer manufactured by National Semiconductor, now part of Texas Instruments. It utilizes F/FAST TTL technology and features two independent multiplexing circuits within a single package. The device operates with a nominal supply voltage of 5 V and supports input signals from four lines per function to a single true output. Designed for military-grade reliability, it functions within an extended temperature range of -55 °C to 125 °C. The component is housed in a 16-pin ceramic Dual In-Line Package (CDIP) with through-hole terminals, ensuring robust performance in demanding environments.

Feature Summary

• Dual independent 4-to-1 multiplexing functionality
• Military-grade temperature rating for extreme environments
• Fast TTL logic technology for high-speed operation
• Hermetic ceramic packaging for durability

Applications

• Military avionics signal routing
• Industrial control system data selection
• High-reliability telecommunications equipment
• Aerospace instrumentation multiplexing

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'MLS' matches your requirement for military lot traceability or screening standards. Ensure the ceramic DIP package is compatible with your assembly process. Check for RoHS compliance status if required by your facility regulations, noting that older military parts may not be compliant. Validate the datasheet version against current TI documentation.

Selection Notes

Select this component when dual independent multiplexing is required in harsh environments. The F/FAST series offers faster switching speeds than standard LS-TTL equivalents. The ceramic CDIP package provides superior hermetic sealing compared to plastic variants. Consider this part for applications requiring MIL-STD-883 screening levels. Ensure the 5 V supply voltage aligns with your system design constraints.

Part Context

This component belongs to the 54F series of logic devices, which are characterized by fast propagation delays suitable for high-performance digital systems. The 54 prefix indicates military temperature range qualification, distinguishing it from commercial 74-series counterparts. As a multiplexer, it consolidates multiple input signals into a single output stream based on select line inputs. The DM designation typically refers to the ceramic DIP package style used in aerospace and defense applications.

Replacement Considerations

Direct replacements include other 54F153 variants with identical pinouts and electrical characteristics. Verify that substitute parts maintain the same military temperature range and ceramic packaging requirements. Cross-reference with Texas Instruments documentation for updated equivalent part numbers. Ensure any alternative maintains the dual 4-to-1 multiplexer configuration.
