SN74LVC157ADG4

Overview

The SN74LVC157ADG4 is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, belonging to the LVC logic family. It integrates four independent multiplexers in a single package, providing efficient signal routing capabilities. The device operates within a supply voltage range of 1.65 V to 3.6 V, ensuring compatibility with low-voltage digital systems. It features a propagation delay of 7 ns and supports an operating temperature range from -40°C to +125°C. The component is housed in a 16-pin TSSOP package, designed for surface-mount technology applications requiring compact footprints.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for consolidated signal selection
• Operates across a wide supply voltage range from 1.65 V to 3.6 V
• Supports high-speed data switching with a propagation delay of 7 ns
• Rated for extended industrial temperature environments up to 125°C

Applications

• Data routing in portable battery-powered electronic devices

Procurement Notes

Verify the specific suffix 'DG4' against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match project requirements. Ensure the ordering information aligns with the current product status and availability. Cross-reference the package type and thermal specifications with your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required in a space-constrained design. The LVC series offers lower power consumption compared to older logic families while maintaining adequate speed for most digital applications. Consider the 1.65 V minimum supply voltage if interfacing with ultra-low-power microcontrollers or sensors.

Part Context

This part belongs to the SN74LVC157A series of quadruple multiplexers manufactured by Texas Instruments. The LVC (Low Voltage CMOS) family is designed for high-speed operation with reduced power dissipation. The 'DG4' suffix typically denotes a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Replacement Considerations

Compatible alternatives include the SN74LVC157APWR and SN74LVC157ANSR. Verify that substitute parts maintain identical pin configurations and electrical parameters to ensure direct interchangeability without circuit redesign.
