DESCRIPTION:
The QS34XVH245 HotSwitch is a high bandwidth 32-bit bus switch. The
QS34XVH245 has very low ON resistance, resulting in under 250ps propa-
gation 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 termnals.
The combination of near-zero propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS34XVH245 ideal for high performance
communications applications.
The QS34XVH245 is characterized for operation from-40
°
C to +85
°
C.
