IDTQS3125
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• Pin compatible with the 74’125 function
• Zero propagation delay, zero added ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Available in QSOP and SOIC packages
APPLICATIONS:
• 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 QS3125 provides a set of four high-speed low resistance CMOS
switches connecting inputs to outputs without propagation delay and without
generating additional ground bounce noise. Individual enables (OE) are
used to turn on the switches. The QS3125 is ideal for signal and control
switching since the device adds no noise, ground bounce, propagation
delay, or significant power consumption to the system. The QS3125 can also
be used for analog switching applications such as video.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
The QS3125 is characterized for operation at -40°C to +85°C.
