IDTQS3800 HIGH-SPEED CMOS 10-BIT QUICKSWITCH WITH PRECHARGED OUTPUTS PRODUCTS HIGH-SPEED CMOS 10-BIT QUICKSWITCH WITH PRECHARGED OUTPUTS INDUSTRIAL TEMPERATURE RANGE IDTQS3800 FEATURES: • 5Ω bidirectional switches connect inputs to outputs • Zero propagation delay, zero ground bounce • Undershoot clamp diodes on all switch and control inputs • Outputs precharge voltage to minimize signal distortion during live insertion • TTL-compatible input and output levels • Available in QSOP package DESCRIPTION: The QS3800 is a 10-bit high-speed CMOS bus switch controlled by a single enable ON input. When ON is low, the switch is on and port A is connected to port B. When ON is high, the switch between port A and port B is open and port B is precharged to the bias voltage. The low ON resistance 5Ω of the QS3800 allows inputs to be connected to outputs without adding propagation delay and without generating additional noise. The QS3800 also precharges the B port to a user-selectable bias voltage to minimize live insertion noise, which is useful in VME bus applications.

INDUSTRIAL TEMPERATURE RANGE

IDTQS3800

FEATURES:
• 5Ω bidirectional switches connect inputs to outputs
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Outputs precharge voltage to minimize signal distortion
during live insertion
• TTL-compatible input and output levels
• Available in QSOP package

DESCRIPTION:

The QS3800 is a 10-bit high-speed CMOS bus switch controlled by a single enable ON input. When ON is low, the switch is on and port A is connected to port B. When ON is high, the switch between port A and port B is open and port B is precharged to the bias voltage. The low ON resistance 5Ω of the QS3800 allows inputs to be connected to outputs without adding propagation delay and without generating additional noise. The QS3800
also precharges the B port to a user-selectable bias voltage to minimize live
insertion noise, which is useful in VME bus applications.

The QS3800 is characterized for operation at -40°C to +85°C.
