JD54LS153SEA

Overview

The JD54LS153SEA is a dual 4-line to 1-line data selector/multiplexer manufactured by National Semiconductor. It utilizes TTL logic technology and operates on a 5 V supply voltage. The device features two independent multiplexers, each selecting one of four data inputs based on address lines. It is housed in a ceramic DIP package with 16 terminals, designed for military-grade reliability across an extended temperature range.

Feature Summary

• Integrates two independent 4-to-1 multiplexing circuits within a single component
• Supports high-reliability operation suitable for demanding environments
• Provides direct selection of input data streams via control logic

Applications

• Military-grade digital signal routing systems
• High-reliability data acquisition hardware
• Industrial control logic implementation

Procurement Notes

Verify the specific suffix 'SEA' against official National Semiconductor documentation to confirm exact pinout and material specifications. Ensure compatibility with existing MIL-STD-883 Class B requirements if military qualification is mandated. Cross-reference datasheets for any revisions that may affect mechanical dimensions or electrical characteristics compared to standard variants.

Selection Notes

Select this component when dual independent multiplexing is required in a ruggedized environment. The ceramic construction offers superior thermal stability and hermetic sealing compared to plastic packages. Consider this part for designs where long-term reliability and resistance to harsh conditions are critical design constraints.

Part Context

This part belongs to the SN54LS153 family of dual 4-line data selectors. It shares functional similarities with other LS-series logic devices but distinguishes itself through its military-grade packaging and environmental ratings. It serves as a core switching element in complex digital architectures requiring multiple independent data paths.
