HIGH-SPEED CMOS

QUICKSWITCH 32-BIT

MULTIWIDTH™ BUS SWITCHES

DESCRIPTION:

devicesandprovidesasetof32high-speedCMOScompatiblebusswitches

in a flow-through pinout. This device is available in the MillipaQ package,

the worlds first small outline 32-bit solution. The low ON-resistance of the

QS34X2245 allows inputs to be connected to outputs without adding

propagation delay and without generating additional ground bounce noise.

Internal 25

Ω resistors reduce reflection noise in high-speed applications.

When Output Enable (OEn) is low, the switches are turned on, connecting

bus A to bus B. When OEn is high, the switches are turned off. This device

QuickSwitch devices provide speeds an order of magnitude faster than

conventional logic devices.

The QS34X2245 is characterized for operation at -40°C to +85°C.
