IDTQS3126
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• Bidirectional switches connect inputs to outputs
• Pin compatible with the 74’126 function
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Available in QSOP and SOIC packages
APPLICATIONS:
• Active high enabling
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Power conservation
• Capacitance reduction and isolation (mass storage, work
stations)
• Logic replacement (data processing)
• Clock gating
• Bus isolation
DESCRIPTION:
The QS3126 provides a set of four high-speed CMOS switches connect-
ing inputs to outputs. The low ON resistance of the QS3126 allows inputs
to be connected to outputs without propagation delay and without generating
additional ground bounce noise. Individual active high enables (OE) are
used to turn the switches on. The QS3126 is ideal for signal and control
switching since the device adds no noise, ground bounce, propagation
delay, or significant power consumption to the system.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS3126 is characterized for operation at -40°C to +85°C.
