SN74LVC2G157DCUR

Signal Switches, Multiplexers, Decoders Overview

The SN74LVC2G157DCUR is a dual data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features low on-resistance for minimal signal attenuation. The device supports high-speed operation with propagation delays typically under 5 ns at 3.3 V. It includes overvoltage protection on inputs, allowing safe interfacing with 5 V systems while powered by lower voltages. Packaged in an 8-pin VSSOP, it is designed for portable applications requiring small form factors.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'DCUR' corresponds to the tape-and-reel packaging configuration intended for automated assembly processes. Confirm RoHS compliance status as per current manufacturer declarations. Ensure the ordering part number matches the exact package type and temperature grade required for your design specifications before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent 2-to-1 multiplexing is required in a minimal footprint. It is suitable for designs needing overvoltage tolerance on input lines without external protection components. Consider the VSSOP package constraints regarding thermal dissipation and PCB space availability compared to larger packages like SOIC or TSSOP.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the LVC (Low Voltage CMOS) family, known for high speed and low power consumption. It is functionally compatible with other 74LVC series logic devices. The DCUR designation indicates a specific surface-mount package variant optimized for high-volume manufacturing. It serves as a standard solution for basic data selection tasks in modern digital circuits.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct pin-compatible alternatives within the same LVC family from Texas Instruments or other major manufacturers. Verify that any substitute maintains the same voltage range and I/O characteristics. Ensure the replacement package matches the existing PCB footprint if reflow soldering is planned.
