QS3VH253 - Renesas

QS3VH253 2.5V / 3.3V DUAL 4:1 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH

The QS3VH253 HotSwitch Dual 4:1 multiplexer/demultiplexer is a high bandwidth bus switch. The QS3VH253 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The Select (Sx) inputs control the data flow. The multiplexers/demultiplexers are enabled when the Enable (EA, EB) inputs are low. In the ON state, the switches can .
