SN74LS139ANE4

Overview

The SN74LS139ANE4 is a dual 2-line to 4-line decoder/demultiplexer from the Texas Instruments 74LS series. It features Schottky clamping for high performance and operates within a standard voltage range of 4.75 V to 5.25 V. The device is housed in a 16-pin PDIP package with an operating temperature range of 0°C to 70°C. It complies with RoHS standards and utilizes NIPDAU lead finish.

Feature Summary

• Dual independent decoders or demultiplexers integrated into a single package
• Schottky-clamped architecture designed for high-speed switching performance
• Standard TTL input logic levels compatible with general digital systems

Applications

• Address decoding for memory and I/O selection
• Demultiplexing data streams to multiple output lines
• Control signal distribution in industrial logic circuits

Procurement Notes

Verify the specific ordering suffix against the official Package Option Addendum to confirm the exact physical package, lead finish, and moisture sensitivity level. Ensure the procurement channel sources parts matching the active production status listed by Texas Instruments to avoid obsolete variants.

Selection Notes

Select this component when dual low-power Schottky decoding functions are required in through-hole designs. Compare against the SN74LS139AN for identical electrical characteristics but different packaging configurations. Confirm that the 74LS series speed and power consumption align with the system requirements before finalizing the design.

Part Context

This part belongs to the broader 74LS139 family manufactured by Texas Instruments. The family includes various package options such as SOIC, SOP, and military-grade ceramic packages like the SN54LS139AJ. The 'E4' suffix indicates compliance with specific environmental and material definitions established by the manufacturer.
