DESCRIPTION:
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 pass signals up to 5V. In the OFF state, the switches offer very
high impedance at the terminals.
The combination of near-zero propagation delay, high OFF impedance,
and over-voltage tolerance makes the QS3VH253 ideal for high perfor-
mance communication applications.
The QS3VH253 is characterized for operation from -40°C to +85°C.
