IDTQS3R861
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
• Available in SOIC and QSOP packages
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 QS3R861 provides a set of ten high-speed CMOS TTL-compatible
bus switches. The very low ON resistance (2.5Ω) of the QS3R861 allows
inputs to be connected without adding propagation delay and without
generating additional ground bounce noise. The Bus Enable (BE) signal
turns the switches on.
The low ON resistance of the QS3R861 makes it ideal for PCI hot-
plugging or hot-swapping applications.
The QS3R861 is characterized for operation at -40°C to +85°C.
