DESCRIPTION:
QS32XVH245 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 the LVTTL-compatible Output Enable (OEx) signal 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.
over-voltage tolerance makes the QS32XVH245 ideal for high performance
communications applications.
