DESCRIPTION:
QS3VH800 has very low ON resistance, resulting in under 250ps propagation
delay through the switch. The QS3VH800 precharges the B port to a user
selectable bias voltage (V
can be turned ON under the control of the LVTTL-compatible Output Enable
(OE) signal for bidirectional data flow with no added delay or ground bounce.
In the ON state, the switches can pass signals up to 5V. In the OFF state, the
switches offer very high impedence at the terminals.
over-voltage tolerance makes the QS3VH800 ideal for high performance
communication applications.
