SN74LVC157ADBR

Overview

The SN74LVC157ADBR is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments' LVC logic family. It features four independent multiplexers in a single package, operating within a supply voltage range of 2 V to 3.6 V. The device utilizes a 16-pin TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of approximately 7 ns and compliance with RoHS standards for environmental safety.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for efficient signal routing
• Operates across a wide supply voltage range suitable for low-power applications
• Supports high-speed data selection with low propagation delay
• Designed for surface-mount assembly in compact electronic systems

Applications

• Data routing in embedded control systems
• Signal selection in industrial instrumentation
• Input multiplexing in consumer electronics
• Address/data bus switching in computing hardware

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the TSSOP-16 package and tape-and-reel orientation as defined by Texas Instruments documentation. Confirm that the component meets the required RoHS compliance status for your region. Ensure that the operating temperature range of -40°C to +85°C aligns with your system's thermal design constraints before finalizing procurement.

Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required within a single integrated circuit footprint. The LVC series offers compatibility with 3.3 V logic levels while maintaining operation down to 2 V. Consider the TSSOP-16 package dimensions for PCB layout constraints. Verify that the input voltage levels match the source signals to ensure proper logic threshold recognition.

Part Context

This part belongs to the SN74LVC157A family of quadruple multiplexers manufactured by Texas Instruments. The LVC (Low Voltage CMOS) series is designed for high-speed digital applications requiring low power consumption. The 'A' variant typically denotes enhanced performance or updated specifications compared to earlier generations. The 'DBR' suffix specifically identifies the TSSOP-16 package type and reel packaging configuration.

Replacement Considerations

Compatible substitutes include SN74LVC157APWR (TSSOP-16) and SN74LVC157ADREP (SOIC-16). Verify pinout compatibility and package dimensions before substitution. Automotive-grade variants such as SN74LVC157A-Q1 may offer extended reliability but require validation against specific automotive standards.
