DESCRIPTION:
bus switch. The QS3VH16862 has very low ON resistance, resulting in
under 250ps propagation delay through the switch. The switches are
controlled by independent active low enable (BEx) LVTTL compatible
control inputs. 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.
and over-voltage tolerance makes the QS3VH16862 ideal for high perfor-
mance communications applications.
