DESCRIPTION:
The QS32XVH384 HotSwitch is a high bandwidth, 20-bit bus switch. The
QS32XVH384 has very low ON resistance, resulting in under 250ps
propagation delay through the switch. Four 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 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 impedance, and
over-voltage tolerance makes the QS32XVH384 ideal for high performance
communications applications.
The QS32XVH384 is characterized for operation from -40°C to +85°C.
