SN74LS253NSR

Overview

The SN74LS253NSR is a dual four-input multiplexer manufactured by Texas Instruments, belonging to the SN74LS series. It features two independent multiplexing circuits, each with four data inputs and one output. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in a 16-SOIC package. It functions as a single-function gate designed for signal routing applications.

Feature Summary

• Contains two independent 4-to-1 multiplexing channels
• Provides selectable data routing via address lines
• Supports standard surface-mount packaging

Applications

• Data selection and routing in digital systems
• Signal path switching in logic circuits
• Multiplexing input signals for processing

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required logic family standards. Confirm RoHS compliance status through manufacturer datasheets before procurement. Validate that the ordering code corresponds exactly to the intended surface-mount configuration.

Selection Notes

Select this component when dual independent multiplexing functionality is required within a compact footprint. Consider the LS logic family characteristics regarding speed and power consumption relative to system requirements. Verify compatibility with available address control lines and ensure the operating temperature range meets environmental constraints.

Part Context

This part belongs to the SN74LS253 family of dual four-input multiplexers. It shares functional similarities with other devices in the 74LS series but offers distinct dual-channel architecture. The NSR suffix typically indicates a specific reel-based packaging format for automated assembly processes.
