Overview
The Texas Instruments JM38510/65852BFA is a military-grade SN54HC138 3-line to 8-line decoder and demultiplexer. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to 125 °C. The device features active-low outputs, three enable inputs for cascading or data reception, and low input current. It is designed for high-speed memory decoding and data transmission systems.
Feature Summary
- Provides 3-to-8 decoding functionality with active-low selected outputs
- Incorporates three enable inputs (one active-high, two active-low) to simplify system expansion
- Designed for high-performance memory-decoding applications requiring short propagation delays
Applications
- High-speed memory decoders
- Data-transmission systems
- LED matrix displays
Procurement Notes
Verify the specific MIL-PRF-38535 qualification class and lot traceability requirements against your procurement specifications. Confirm that the package type matches the required form factor for your assembly process. Ensure environmental testing standards align with the -55 °C to 125 °C operating range defined in the datasheet.
Selection Notes
Select this component when a radiation-hardened or high-reliability CMOS decoder is required for harsh environments. Compare the HC series speed and power consumption against LS or ALS alternatives if lower power is critical. Verify that the 2 V to 6 V supply range accommodates your system's voltage rails without level shifting.
Part Context
This part belongs to the SN54HC138 family, which is the military-grade counterpart to the commercial SN74HC138. It utilizes CMOS technology to achieve low power consumption while maintaining high-speed performance. The device is manufactured by Texas Instruments under the JM38510 military specification numbering system.
