DESCRIPTION:
The QS34XVH245 HotSwitch is a high bandwidth 32-bit bus switch. The
QS34XVH245 has very low ON resistance, resulting in under 250ps
propagation delay through the switch. The switches can be turned ON
under the control of individual LVTTL-compatible Output Enable (OEx)
signals for bidirectional data flow with no added delay or ground bounce. In
the ON state, the switches can pass 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 QS34XVH245 ideal for high perfor-
mance communications applications.
The QS34XVH245 is characterized for operation from -40°C to +85°C.
