The QS32X861 provides two sets of ten high-speed CMOS TTLcompatiblebus switches. The low ON resistance of the QS32X861 allowsinputs to be connected to outputs without adding propagation delay andwithout generating additional ground bounce noise. The Bus Enable (
BEn
)signals turn the switches on.
The QS32X861 bus switch is ideal for switching digital buses, as well asfor hotplug buffering and 5V to 3V conversion.
The QS32X861 is characterized for operation at -40to +85.
