Zero propagation delay, zero ground bounce
QS32XR245 is a 16-bit version of QS3R245
Flow-through pinout for easy layout
Undershoot clamp diodes on all switch and control inputs
TTL-compatible control inputs
Available in 40-pin QVSOP package
IDTQS32XR245
DESCRIPTION:
APPLICATIONS:
鈥?Low resistance applications
鈥?Hot-swapping, hot-docking (low resistance for PCI and
Compact PCI applications)
鈥?Voltage translation (5V to 3.3V)
鈥?Capacitance reduction and isolation
鈥?Power conservation
鈥?Logic replacement (data processing)
鈥?Clock gating
The QS32XR245 is a member of the MultiWidth
TM
family of QuickSwitch
devices and provides a set of 32 high-speed low resistance CMOS
compatible bus switches in a flow-thru pinout. This device is available in the
MillipaQ package, the world's first small outline 16-bit solution. The low on-
resistance of the QS32XR245 allows inputs to be connected to outputs
without adding propagation 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 16/32 bit applications where board space
is at a premium.The low resistance of QS32XR245 makes it ideal for PCI
hot docking application.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS32XR245 is characterized for operation at -40擄C to +85擄C.
