QUADRUPLE BUS SWITCH WITH

INDIVIDUAL ACTIVE HIGH ENABLES

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

tobeconnectedtooutputswithoutpropagationdelayandwithoutgenerating

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.
