74LVC2G157DCUTE4

Signal Switches, Multiplexers, Decoders Overview

The SN74LVC2G157DCUTE4 is a single 2-line to 1-line data selector multiplexer from Texas Instruments, designed for operation within a supply voltage range of 1.65 V to 5.5 V. It features a common strobe input that controls the routing of data from two sources to true and complementary outputs. The device supports partial-power-down applications via Ioff circuitry, which disables outputs to prevent backflow current when powered down. It provides symmetric output drive capabilities up to ±24 mA at 3.3 V and includes robust ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix DCUTE4 corresponds to the VSSOP package variant. Confirm RoHS compliance status and environmental classification details directly with the manufacturer or authorized distributors. Ensure design compatibility with the specified operating temperature range of -40°C to 85°C. Validate pinout alignment with the 8-pin VSSOP footprint during PCB layout.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring a compact single-channel multiplexer with wide voltage tolerance. The 5.5 V input tolerance allows direct interfacing with 5 V logic systems while operating at lower core voltages. Consider the NanoFree™ packaging for space-constrained layouts. Evaluate the propagation delay specifications against system timing requirements across the intended supply voltage range.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74LVC2G157 family of data selectors manufactured by Texas Instruments. The LVC series is characterized by high-speed operation and low power consumption. The DCUTE4 designation specifically identifies the VSSOP package configuration within this product line, distinguishing it from SSOP or DSBGA variants available in the same functional family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Consult the TI Package Option Addendum for alternative package versions such as SN74LVC2G157DCTRE4 or SN74LVC2G157YZPR. Verify electrical equivalence and pinout compatibility before substitution. Cross-reference with other single 2-to-1 multiplexers if package constraints differ.

Signal Switches, Multiplexers, Decoders FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device.

What is the input voltage tolerance?

Inputs accept voltages up to 5.5 V, allowing the device to be used as a down translator from 5 V logic levels.
