DESCRIPTION:
The QS3VH384 HotSwitch is a high bandwidth, 10-bit bus switch. The
QS3VH384 has very low ON resistance, resulting in under 250ps propagation
delay through the switch. Two banks of five switches are controlled by
independent (xOE), LVTTL compatible signals for bidirectional data flow with
no added delay or ground bounce. In the ON state, the switch 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 impedance, and
over-voltage tolerance makes the QS3VH384 ideal for high performance
communications applications.
The QS3VH384 is characterized for operation from -40°C to +85°C.
