DESCRIPTION:
The QS32X2384 provides a set of twenty high-speed CMOS TTL-
compatible bus switches. The QS32x2384 also includes internal 25Ω
series termination resistors to reduce reflection noise in high-speed
applications. The Bus Enable (BE) signals turn the switches on. Four Bus
Enable signals are provided, one for each of five bits of the 20-bit bus. The
‘384 family of QuickSwitch products is ideal for switching wide digital buses,
as well as hotplug buffering, and 5V to 3V conversion.
The QS32X2384 is characterized for operation at -40°C to +85°C.
