PI3L100QEX

Analog Switches - Special Purpose Overview

The PI3L100QEX is a quad 2:1 multiplexer/demultiplexer LAN switch manufactured by Diodes Incorporated. It features three-state outputs and operates on a single 3.3V supply (±10%). The device supports data rates exceeding 200 MHz with a -3dB bandwidth of 213 MHz. Key electrical parameters include a typical on-resistance of 5Ω, quiescent power supply current of 0.1µA, and crosstalk of -90 dB at 30 MHz. It is housed in a 16-pin 150-mil wide plastic QSOP package.

Analog Switches - Special Purpose Feature Summary

• Replaces mechanical relays in low voltage LAN applications
• Ultra-low quiescent power consumption
• Low insertion loss and high off-isolation
• Wide-bandwidth capability for various LAN standards

Analog Switches - Special Purpose Applications

• Switching between 10 Base-T and 100 Base-T standards
• Loopback configurations
• Line termination circuits
• Line clamp implementations

Analog Switches - Special Purpose Procurement Notes

Verify the component marking against the datasheet to confirm the PI3L100QEX designation. Ensure the package matches the 16-pin QSOP specification. Check for RoHS compliance indicators as the 'E' suffix denotes Pb-free and Green status. Confirm the tape and reel packaging format if required for automated assembly processes.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring signal switching between different LAN standards such as 10/100 Base-T. It is suitable for replacing mechanical relays where low power and small form factor are critical. Ensure the operating voltage remains within the 3.3V ±10% range to maintain optimal on-resistance characteristics.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3L100 series of LAN switches produced by Pericom Semiconductor, now part of Diodes Incorporated. The QEX suffix specifically indicates the 16-pin QSOP package variant supplied in tape and reel format. It is designed for general-purpose analog switching in network infrastructure equipment.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements must match the quad 2:1 mux/demux architecture and 16-pin QSOP footprint. Verify that alternative components support the same 3.3V supply voltage and meet the required bandwidth specifications for 10/100 Base-T applications.
