Overview

The TS5A3157DCKR is a high-speed, single-pole double-throw (SPDT) analog switch designed to operate from 1.65V to 5.5V. It features a high 300MHz bandwidth and low 10-ohm on-state resistance, making it suitable for both analog and digital signal switching in space-constrained designs. The device is housed in a compact 6-pin SC-70 package and offers low power consumption of 10 microamps maximum across its temperature range.

Why Choose This Part

The component offers an excellent balance of 300MHz bandwidth and low 7pC charge injection, minimizing signal distortion during switching transitions. Its 5V-tolerant control inputs and broad supply range allow for seamless integration into various mixed-voltage systems without additional level shifting.

Applications

Audio Signal Routing
Switching between different audio sources or routing signals to different speakers with low total harmonic distortion.
Portable Instrumentation
Selecting between multiple sensor inputs or calibration references in battery-powered handheld devices.
Communication Systems
High-bandwidth signal multiplexing in telecommunication equipment where low crosstalk is required.
Digital Logic Multiplexing
Routing high-speed digital control signals while maintaining signal integrity at lower operating voltages.

Getting Started

To evaluate this part, ensure the V+ supply is decoupled with a 0.1uF ceramic capacitor placed close to the SC-70 package pins. When layouting for high-frequency signals, minimize trace lengths on the NO, NC, and COM pins to preserve the 300MHz bandwidth and reduce parasitic capacitance.
