INDUSTRIAL TEMPERATURE RANGE
IDTQS3R384
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• 2.5Ω bidirectional switches connect inputs to outputs
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Two enables control five bits each
• Available in QSOP package
APPLICATIONS:
• Hot-swapping, hot-docking (low resistance for PCI and
Compact PCI applications)
• Voltage translation (5V to 3.3V)
• Power Conservation
• Capacitance reduction and isloation
• Bus Isolation
• Clock Gating
DESCRIPTION:
The QS3R384 provides a set of ten high-speed CMOS TTL-compatible
bus switches. Two banks of 5 switches are controlled by independent Bus
Enable (BE) signals. The very low RON resistance (2.5Ω) of the QS3R384
allows inputs to be connected without adding propagation delay and without
generating additional ground bounce noise.
The low ON resistance of the QS3R384 makes it ideal for PCI hot-
plugging or hot-swapping applications.
The QS3R384 is characterized for operation at -40°C to +85°C.
