SN74LVC1G3157DBVR-EV

Overview

The SN74LVC1G3157DBVR-EV is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by EVVO. It operates on a supply voltage range of 1.65V to 5.5V and supports bidirectional signal transmission with amplitudes up to VCC. The device features low power consumption, high transmission speed, and an input select terminal with over-voltage protection allowing inputs up to 7V. It provides break-before-make switching to prevent short circuits and includes ESD protection exceeding JESD 22 standards. The component is designed for applications requiring precise signal routing in compact systems.

Feature Summary

Supports bidirectional analog and digital signal transmission across the full supply voltage range
Features over-voltage protection on the select input terminal up to 7V
Provides break-before-make switching action to prevent channel shorting
Offers high bandwidth and linearity suitable for video and audio signals

Applications

Signal gating and chopping circuits
Modulation and demodulation in modem applications
Multiplexing for analog-to-digital and digital-to-analog conversion systems
Clock switching and data selection switches
NTSC/PAL video, audio, SPDIF, and HDTV signal routing

Procurement Notes

Verify that the manufacturer designation matches EVVO rather than Texas Instruments, as the base part number is commonly associated with TI. Confirm the package type is SOT-23-6 and check for specific marking codes corresponding to the EVVO revision. Ensure the operating temperature range meets the -55°C to +125°C requirement if used in harsh environments.

Selection Notes

Select this component when a single SPDT switch is required for low-power CMOS logic level translation. It is suitable for designs needing high bandwidth up to 350MHz and low charge injection. Consider the thermal resistance of 270°C/W for heat dissipation calculations. Ensure the control voltage levels are compatible with the specified VIH and VIL thresholds for the chosen supply voltage.

Part Context

This component belongs to the SN74LVC1G3157 series of analog switches. While the base model is widely produced by Texas Instruments, this specific variant is manufactured by EVVO. It shares the same functional architecture as other LVC series switches but may differ in specific electrical tolerances or packaging markings. It serves as a general-purpose solution for signal path management in portable and industrial electronics.
