Overview
The JM38510/30701SFA is a military-grade 3-line to 8-line decoder/demultiplexer from Texas Instruments, belonging to the LS series. It features inverted outputs and utilizes bipolar TTL technology housed in a CDFP-16 package. The device operates within a temperature range of -55°C to 125°C and supports standard logic voltage levels. Designed for high-reliability applications, it provides eight distinct output lines controlled by three address inputs.
Feature Summary
- Provides decoding functionality for three binary inputs into eight mutually exclusive outputs
- Features inverted logic outputs suitable for specific interface requirements
- Constructed with bipolar technology for robust performance in harsh environments
- Certified for extended industrial and military temperature ranges
Applications
- Military avionics systems requiring radiation-hardened or high-reliability logic components
- Spacecraft telemetry and command distribution networks
- Defense communication equipment addressing modules
- Industrial control systems operating in extreme thermal conditions
Procurement Notes
Verify the specific suffix designation (e.g., SFA) against the manufacturer's current datasheet to ensure correct pinout and electrical characteristics. Confirm that the component meets all required environmental certifications for your application. Check for lead content compliance if RoHS restrictions apply to your assembly process. Ensure proper handling procedures are followed due to the ceramic package type.
Selection Notes
Select this component when a hardened 3-to-8 decoder with inverted outputs is required. Compare propagation delays and power consumption against other LS-series alternatives if system constraints are tight. Consider the physical footprint of the CDFP-16 package during PCB layout. Verify compatibility with existing control logic voltage levels before integration.
Part Context
This part is part of the JM38510 family, which represents military-standard versions of Texas Instruments' logic devices. These components are designed to meet stringent MIL-PRF-38534 specifications. The SN54LS138-SP is the commercial space-grade equivalent often referenced in cross-reference lists. This family ensures reliability in aerospace and defense sectors.
Replacement Considerations
Direct replacements include other military-grade 54LS138 variants from qualified manufacturers. Cross-reference with SN54LS138-SP for similar functional specifications. Verify pin compatibility and electrical parameters before substituting. Ensure any alternative maintains the same temperature rating and package style for mechanical fit.
