Overview
The SN74LS139ANSLE is a dual 2-line to 4-line decoder/demultiplexer from Texas Instruments' LS logic family. It features Schottky clamping for high performance and operates within a standard voltage range of 4.75V to 5.25V. The component is housed in a 16-pin SOIC package with a maximum length of approximately 10.2 mm. It supports a load capacitance of 15 pF and contains two independent decoding circuits. The device is RoHS compliant, lead-free, and designed for general-purpose digital logic applications requiring reliable signal decoding.
Feature Summary
- Dual independent 2-to-4 line decoding functionality
- Schottky clamped structure for enhanced high-performance operation
- Standard input regulation compatible with TTL logic levels
Applications
- High-performance memory decoding systems
- Data routing and demultiplexing circuits
- General-purpose digital logic interface designs
Procurement Notes
Verify the specific suffix 'SLE' against official Texas Instruments documentation to confirm package type and environmental compliance status. Ensure the ordering part number matches the required SOIC-16 configuration and temperature range specifications before procurement.
Selection Notes
Select this component when dual independent decoding channels are required within a compact surface-mount footprint. The LS series offers a balance of speed and power consumption suitable for standard digital applications. Confirm compatibility with existing system voltage levels and logic families during the design phase.
Part Context
This part belongs to the SN74LS139A family of decoders and demultiplexers. It shares functional similarities with other variants like SN74LS139AN and SN74LS139ADR but differs in packaging and manufacturing revisions. The LS designation indicates Low-power Schottky technology, providing improved switching characteristics compared to standard TTL equivalents.
Replacement Considerations
Direct substitutes include SN74LS139AN (DIP-16) and SN74LS139ADR (SOIC-16). Verify pinout compatibility and ensure the replacement variant meets the same electrical and mechanical specifications for the target application.
