IDTQS32XVH384

2.5V/3.3V 20-BIT HIGH

BANDWIDTH BUS SWITCH

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 bidirec-

tional 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 perfor-

mance communications applications.

The QS32XVH384 is characterized for operation from -40

°C to +85°C.
