QUICKSWITCH 32-BIT
MULTIWIDTH BUS SWITCHES
DESCRIPTION:
The QS34X245 is a member of the MultiWidth
TM
famly of QuickSwitch
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 world's first small outline 32-bit solution. The low ON-resistance of the
QS34X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. 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 premum
QuickSwitch devices provide speeds an order of magnitude faster than
conventional logic devices.
The QS34X245 is characterized for operation at -40°C to +85°C.
