DESCRIPTION:

The QS3125 provides a set of four high-speed low resistance 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 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.

QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices.

The QS3125 is characterized for operation at -40°C to +85°C.

FEATURES:

• Enhanced N channel FET with no inherent diode to Vcc

• Pin compatible with the 74’125 function

• Zero propagation delay, zero added ground bounce

• Undershoot clamp diodes on all switch and control inputs

• Available in QSOP and SOIC packages

APPLICATIONS:

• Hot-swapping, hot-docking

• Voltage translation (5V to 3.3V)

• Power conservation

• Capacitance reduction and isolation (mass storage, work stations)

• Logic replacement (data processing)

• Clock gating

• Bus isolation
