JM38510/65802B2A

Overview

JM38510/65802B2A is a military-grade 3-to-8 decoder and demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features active-low outputs selected by three binary inputs (A, B, C). The device includes three enable inputs (one active-high G1, two active-low G2A/G2B) for cascading or data reception control. It is housed in a 20-pin LCCC package with an operating temperature range of -55 °C to 125 °C.

Feature Summary

• Provides 3-to-8 decoding functionality with single active-low output selection
• Incorporates three enable pins to simplify system expansion and data routing
• Designed for high-speed memory decoders and data-transmission systems

Applications

• High-performance memory decoding
• Data-routing applications
• LED matrix display column selection

Procurement Notes

Verify the specific ordering suffix matches the required package type and environmental rating. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the component meets MIL-PRF-38535 Class B screening levels if applicable. Validate that the active production status aligns with long-term availability needs.

Selection Notes

Select this component when a robust, wide-voltage-range decoder is needed for harsh environments. The HC138 architecture offers low power consumption and balanced output drive suitable for driving multiple loads. Consider the LCCC package for hermetic sealing requirements in aerospace or defense applications where standard plastic packages are insufficient.

Part Context

This part belongs to the SN54HC138 family of 3-line to 8-line decoders/demultiplexers. It shares functional compatibility with commercial SN74HC138 devices but adheres to stricter military reliability standards. The device utilizes CMOS technology to achieve low static power consumption while maintaining fast propagation delays essential for high-speed digital logic systems.

Replacement Considerations

SNJ54HC138FK serves as a direct equivalent within the same product family.
