JM54AC153SFA-RH

Overview

The JM54AC153SFA-RH is a dual 4-input multiplexer manufactured by National Semiconductor, designed for high-speed and low-power applications. It integrates two independent 4-to-1 multiplexers within a single package. The component utilizes AC logic technology to ensure efficient signal routing with minimal power consumption. It is housed in a 16-CFP (Ceramic Flat Pack) package, suitable for robust industrial environments. This device serves as a data selector, allowing multiple input signals to be routed to a single output line based on select inputs.

Feature Summary

• Dual independent 4-to-1 multiplexer architecture
• High-speed operation capabilities
• Low-power consumption design
• Robust ceramic flat pack packaging

Applications

• High-performance logic interfacing
• Data selection systems
• Signal routing in digital circuits

Procurement Notes

Verify the manufacturer origin, as National Semiconductor's logic assets were acquired by Texas Instruments. Confirm the specific suffix 'RH' indicates the required environmental or reliability grade. Ensure the 16-CFP package type matches your board layout requirements. Cross-reference the part number with current distributor catalogs to confirm availability from authorized channels rather than surplus markets.

Selection Notes

Select this component when dual independent multiplexing is required in a compact form factor. The AC series offers a balance of speed and power efficiency compared to older LS or HC families. Consider the ceramic package for harsh environments where plastic packages may be insufficient. Verify voltage levels and propagation delay specifications against system timing constraints before finalizing the design.

Part Context

This part belongs to the 54AC series of high-speed CMOS logic devices originally developed by National Semiconductor. The 54AC family is known for military-grade temperature ranges and high noise immunity. The 153 variant specifically provides dual 4-input multiplexing functionality. The 'JM' prefix typically denotes military or extended temperature range qualification in legacy National Semiconductor nomenclature.

Replacement Considerations

Check for equivalents such as the DM54AC153 or SN74AC153 depending on temperature and package requirements. Note that the 54AC series is often superseded by newer high-speed logic families. Verify pin compatibility and electrical characteristics before substituting with parts from other manufacturers like TI or ON Semiconductor.
