DESCRIPTION:
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.
conventional logic devices.
The QS3125 provides a set of four high-speed low resistance CMOS
QuickSwitch devices provide an order of magnitude faster speed than

... Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the L system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. ...
