FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH862 HotSwitch with 10-bit active high and low enable is
a high bandwidth bus switch. The QS3VH862 has very low ON
resistance, resulting in under 250ps propagation delay through the
switch. The switches are controlled by independent active low enable
(BE) and active high enable (BE) controls. 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.
The combination of near-zero propagation delay, high OFF imped-
ance, and over-voltage tolerance makes the QS3VH862 ideal for high
performance communications applications.
The QS3VH862 is characterized for operation from -40°C to +85°C.
