Overview

The QS3125 provides a set of four high-speed low-resistance CMOS switches connecting inputs to outputs without propagation delay and without generating additional ground bounce noise. The QS3125 is ideal for signal and control switching since the device adds no noise, ground bounce, propagation delay, or significant power consumption to the system. The QS3125 can also be used for analog switching applications such as video. The device operates at -40 °C to +85 °C.
