Overview
The Texas Instruments 5962-9851701QFA is a military-grade SN54AHCT138 decoder/demultiplexer. It converts three binary inputs into eight mutually exclusive outputs. The device operates within a temperature range of -55°C to +125°C. It utilizes a 16-pin Ceramic Flat Pack (CFP) package. This component belongs to the AHCT logic family, ensuring compatibility with standard CMOS interfaces while providing high-speed performance suitable for demanding industrial and aerospace applications.
Feature Summary
- Military-grade reliability for extreme environmental conditions
- Three-line to eight-line decoding capability
- High-speed CMOS technology for efficient operation
Applications
- Aerospace signal routing systems
- Industrial control panel addressing
- Military communication equipment multiplexing
Procurement Notes
Verify the specific suffix QFA confirms the military qualification level and ceramic packaging variant. Ensure the ordering information matches the exact SN54AHCT138 specification sheet. Confirm that the supplier provides traceability documentation required for defense or critical infrastructure procurement processes.
Selection Notes
Select this component when military temperature ratings and radiation hardness are mandatory. The AHCT series offers voltage level translation benefits over standard HCT devices. Consider the CFP package constraints for board space and thermal management requirements in enclosed military enclosures compared to plastic alternatives.
Part Context
This part is a qualified version of the SN54AHCT138. It falls under Texas Instruments' broad portfolio of logic integrated circuits. The 5962 prefix indicates a direct-read military catalog number. It serves as a fundamental building block for address decoding in complex digital systems requiring high reliability.
Replacement Considerations
Direct substitutes include other SN54AHCT138 variants from Texas Instruments with matching military qualifications. Verify pinout compatibility before replacing with generic commercial grade parts, as electrical characteristics may differ significantly under extreme temperatures.
