HIGH-SPEED CMOS DUAL
BUS SWITCH WITH INDIVIDUAL
ACTIVE LOW ENABLES
DESCRIPTION:
The QS3306A provides a set of two high-speed low resistance (3Ω
typical) 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 QS3306A 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
QS3306A can also be used for analog switching applications such as video.
The QS3306A is characterized for operation at -40°C to +85°C.
