HIGH-SPEED CMOS
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
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.
