PI3C3861QE

Signal Switches, Multiplexers, Decoders Overview

The PI3C3861QE is a 10-bit, 2-port bus switch manufactured by Diodes Incorporated. It operates at 2.5V or 3.3V supply voltages and features a low on-resistance of 5 ohms typical. The device supports high bandwidth signals exceeding 400 MHz with near-zero propagation delay. It provides 5V I/O tolerance and permits hot insertion. The component is housed in a 24-pin QSOP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Supports rail-to-rail switching at 2.5V or 3.3V supply levels
• Features 5-ohm on-resistance for direct input-output connection
• Provides 5V I/O tolerance for flexible interface compatibility
• Enables hot insertion without generating ground bounce noise

Signal Switches, Multiplexers, Decoders Applications

• High bandwidth data switching
• Hot docking systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant matches the design requirements, as the Q suffix denotes the 24-pin QSOP form factor. Confirm that the Pb-free and Green packaging designation aligns with environmental compliance standards required for the target assembly process. Ensure the operating voltage range of 2.5V to 3.3V is compatible with the system power rails before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring low latency signal routing between buses. The 10-bit width accommodates parallel data paths efficiently. The 5V tolerant inputs allow interfacing with higher voltage logic levels while maintaining lower internal supply operation. Consider the thermal characteristics of the QSOP package for heat dissipation needs in dense layouts.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the PI3C3861 series of digital bus switches. It is designed to replace mechanical relays or discrete transistor switches in high-speed applications. The integration of two independent 10-bit ports into a single package reduces board space compared to using multiple smaller switches.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The PI3C3861ALE serves as a functional substitute offering identical electrical specifications but utilizes a TSSOP package instead of QSOP.
