SN3257QDYYRQ1 Description

Short technical summary and product information.

The SN3257-Q1 is an automotive-grade CMOS switch from Texas Instruments, offering a 2:1 (SPDT) configuration across four channels. It is designed for high-speed signals with a low propagation delay of 78 ps and a high bandwidth of 2 GHz, making it suitable for multi-lane protocols like SPI and I2S.

 

This device supports bidirectional analog and digital signals with a low on-resistance of 5 Ω. It operates within a wide supply range of 1.5 V to 5.5 V and is compatible with 1.8 V logic. Key features include fail-safe logic, powered-off protection up to 3.6 V signals, and integrated pull-down resistors on logic pins.

 

The SN3257-Q1 is AEC-Q100 qualified for automotive applications, with a temperature grade of 1 (-40°C to +125°C). It is available in a 16-SOT-23-THIN package, suitable for surface mount applications.

 

Applications include SPI, I2S, eSIM, eMMC multiplexing, flash memory sharing, and various automotive systems such as Battery Management Systems (BMS), Telematics Control Units (TCU), and digital cockpits.
