QS3125 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ENABLES INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS QS3125 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE LOW ENABLES DESCRIPTION: FEATURES: Enhanced N channel FET with no inherent diode to Vcc The QS3125 provides a set of four high-speed low resistance CMOS Pin compatible with the 74125 function switches connecting inputs to outputs without propagation delay and without Zero propagation delay, zero added ground bounce generating additional ground bounce noise. Individual enables (OE) are Undershoot clamp diodes on all switch and control inputs used to turn on the switches. The QS3125 is ideal for signal and control Available in QSOP and SOIC packages 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. APPLICATIONS: QuickSwitch devices provide an order of magnitude faster speed than Hot-swapping, hot-docking conventional logic devices. Voltage translation (5V to 3.3V) The QS3125 is characterized for operation at -40C to +85C.
