SN74LS348NSR

Overview

The SN74LS348NSR is an 8-line to 3-line priority encoder manufactured by Texas Instruments. It features three-state outputs and belongs to the SN74LS logic series. The device operates within a supply voltage range of 4.75 V to 5.25 V. It is housed in a 16-pin SOIC package and supports surface-mount installation. The component functions as a single-function gate with eight inputs and three output lines, designed for digital logic applications requiring encoded data conversion.

Feature Summary

• Encodes eight input lines into a corresponding three-bit binary code
• Provides three-state outputs for bus-oriented systems
• Implements priority encoding functionality

Applications

• Digital encoding circuits
• Bus-oriented systems
• Data conversion interfaces

Procurement Notes

Verify the specific suffix 'NSR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with standard 5V logic levels and check for any recent product change notices regarding lead content or manufacturing site updates before finalizing procurement.

Selection Notes

Select this component when an 8-to-3 priority encoding function is required within a 5V logic system. The LS series offers moderate speed suitable for general-purpose digital applications. Consider the SOIC package constraints for PCB layout and ensure the design accommodates the specific input/output characteristics defined in the official electrical parameters.

Part Context

This part is a surface-mount variant of the SN74LS348 priority encoder from Texas Instruments. It is part of the broader 74LS logic family, which utilizes Low-power Schottky technology. The device serves as a fundamental building block for converting multiple input signals into a compact binary representation in digital electronics.

Replacement Considerations

Cross-reference with other SN74LS348 variants from different manufacturers or alternative packages such as DIP or TSSOP if pinout compatibility is required. Verify that substitute parts maintain the same 3-state output capability and logic family characteristics.
