IDTQS3861
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 QSOP and TSSOP packages
DESCRIPTION:
The QS3861 provides a set of ten high-speed CMOS TTL-compatible
bus switches. The low ON resistance (5Ω) of the QS3861 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 QS3861 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Power Conservation
• Capacitance reduction and isloation
• Bus Isolation
• Clock Gating
