INDUSTRIAL TEMPERATURE RANGE
IDTQS32X861
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• 5Ω bidirectional switches connect inputs to outputs
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Available in 48-pin QVSOP package
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Power conservation
• Capacitance reduction and isolation
• Bus isolation
• Clock gating
DESCRIPTION:
The QS32X861 provides two sets of ten high-speed CMOS TTL-
compatible bus switches. The low ON resistance of the QS32X861 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The Bus Enable (BEn)
signals turn the switches on.
The QS32X861 bus switch is ideal for switching digital buses, as well as
for hotplug buffering and 5V to 3V conversion.
The QS32X861 is characterized for operation at -40°C to +85°C.
