TISN74LVC1G3157DCKR
Overview
The SN74LVC1G3157DCKR is a high-speed CMOS single-pole double-throw (SPDT) analog switch designed for 1.65V to 5.5V Vcc operation. It functions as both an analog multiplexer and demultiplexer, featuring a wide 340MHz bandwidth and low 15 Ohm maximum on-state resistance. This component is optimized for rail-to-rail signal handling with break-before-make switching to prevent signal contention.
Why Choose This Part
This switch offers an extremely small SC-70 footprint and very low typical power consumption of 1uA. It provides high-speed operation with typical propagation delays of 0.5ns and handles high-frequency signals up to 340MHz. The device is robust against ESD, exceeding 2000V Human Body Model requirements.
Applications
Key Specifications
Getting Started
To integrate this switch, ensure the control pin (S) is driven by a logic level compatible with Vcc, and decouple the Vcc pin with a 0.1uF ceramic capacitor. The device supports rail-to-rail analog signals, so the input voltage range can extend from GND to Vcc. For prototyping, this SC-70-6 package requires a SMT breakout board or a custom PCB footprint.
