IDTQS3800QG

Overview

The IDTQS3800 is a high-speed CMOS 10-bit QuickSwitch featuring precharged outputs, designed for industrial temperature ranges. It utilizes bidirectional switches with an on-resistance of 5 ohms to connect inputs to outputs without adding propagation delay or generating ground bounce noise. The device includes undershoot clamp diodes and allows the output port to be precharged to a user-selectable bias voltage to minimize signal distortion during live insertion. It operates with TTL-compatible input and output levels.

Feature Summary

• Features zero propagation delay and zero ground bounce through low on-resistance bidirectional switching
• Includes precharged outputs to minimize signal distortion during live insertion events
• Equipped with undershoot clamp diodes on all switch and control inputs

Applications

• VME bus applications requiring live insertion support
• High-speed data bus routing systems
• Industrial temperature range circuit protection

Procurement Notes

Verify the specific package variant QSOP against the datasheet specifications. Confirm that the operating environment remains within the specified industrial temperature range of -40°C to +85°C. Ensure supply voltage conditions align with the 5V ± 10% requirement for optimal performance. Check for any obsolete status updates from the manufacturer regarding this component.

Selection Notes

Select this component when zero propagation delay and minimal ground bounce are critical requirements for the bus architecture. The precharged output feature makes it suitable for systems requiring hot-swap capabilities. Verify that the 10-bit width meets the system data path needs and that the QSOP package fits the available board space constraints.

Part Context

This component belongs to the QuickSwitch product line, which focuses on high-speed CMOS bus switching solutions.
