DESCRIPTION:
devices and provides a set of 32 high-speed CMOS compatible bus switches
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 25Ω 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
is ideally suited for 32/64 bit applications where board space is at a premium.
conventional logic devices.
