Overview
Description
The QS3VH16233 HotSwitch is a 32-bit to 16-bit high bandwidth bus switch, which can multiplex or de-multiplex data. The QS3VH16233 has very low ON-resistance, resulting in under 250ps propagation delay through the switch. This device can be used as two 16-bit to 8-bit multiplexers or as one 32-bit to 16-bit multiplexer. The combination of near-zero propagation delay, high OFF impedance, and overvoltage tolerance also makes the QS3VH16233 ideal for high-performance communications applications. The QS3VH16233 operates from -40 °C to +85 °C.
