1P1G3157QDCKRQ1 Description

Short technical summary and product information.

The Texas Instruments SN74LVC1G3157-Q1 is a single-pole double-throw (SPDT) analog switch designed for automotive applications. It supports a wide operating voltage range from 1.65V to 5.5V, making it versatile for various designs.

 

This device is AEC-Q100 qualified and features a temperature grade of -40°C to +125°C. It offers rail-to-rail signal handling and is specified for break-before-make switching. Key electrical characteristics include a typical on-resistance of approximately 6 Ohms at 4.5V and a high switching speed of typically 0.5ns under specific conditions.

 

The SN74LVC1G3157-Q1 can handle analog and digital signals, allowing transmission of amplitudes up to VCC in either direction. Its applications include signal gating, chopping, modulation, demodulation, and multiplexing for analog-to-digital and digital-to-analog conversion systems.

 

Packaged in a compact SC-70-6 (SOT-363) surface-mount package, this device is supplied on a large reel with a standard quantity of 3,000 units.
