SN74LS153NSR

Overview

The SN74LS153NSR is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It integrates two independent multiplexers within a single package, each capable of selecting one of four data inputs based on binary address signals. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports standard logic levels. It features low power consumption characteristic of the LS series and is housed in a 16-pin SOIC surface-mount package.

Feature Summary

• Integrates two independent 4-to-1 multiplexers for dual-channel data routing
• Provides complete binary decoding for input selection via address lines
• Supports active-low enable functionality for controlled signal gating

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based architectures
• Implementation of combinational logic functions

Procurement Notes

Verify the suffix 'NSR' corresponds to the specific tape-and-reel packaging configuration and SOIC-16 body style. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration. Ensure the operating temperature range aligns with system environmental requirements.

Selection Notes

Select this component when dual independent 4-input multiplexing is required within a compact footprint. Compare propagation delay specifications against system timing constraints. Evaluate pin compatibility with existing PCB layouts if replacing legacy through-hole variants with this surface-mount version.

Part Context

This part belongs to the SN74LS153 family of dual 4-line to 1-line data selectors. It is functionally compatible with other manufacturers' 74LS153 equivalents but maintains Texas Instruments' specific electrical characteristics and packaging standards. The NSR designation indicates a reel-packaged variant suitable for automated assembly processes.

Replacement Considerations

Cross-reference with SN74LS153N for leaded alternatives or SN74HC153 for CMOS upgrades. Verify pinout consistency before substitution. Check voltage tolerance differences between LS and HC families to ensure signal integrity.
