PI3L110LE

Analog Switches - Special Purpose Overview

The PI3L110LE is a 3.3V quad, 2:1 multiplexer/demultiplexer LAN switch manufactured by Diodes Incorporated in a 16-pin TSSOP package. It features a typical on-resistance of 4Ω and supports data frequencies exceeding 350 MHz with a bandwidth greater than 350 MHz. The device operates within a supply voltage range of +3.0V to +3.6V and provides over 2kV ESD protection. Key electrical characteristics include a near-zero propagation delay of 250ps, low crosstalk of -27dB at 250 MHz, and an I/O capacitance of 9pF. It includes undershoot clamp diodes on data and control inputs and supports partial-power-down mode via the IOFF feature.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix 'LE' corresponds to the 16-pin 173-mil wide plastic TSSOP package configuration. Confirm that the component meets Pb-free and Green manufacturing standards as specified in the datasheet documentation before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring a 3.3V quad 2:1 mux/demux for Fast Ethernet transceivers. Ensure the application utilizes CAT 5 or CAT 6 unshielded twisted pair cables through isolation transformers. Verify compatibility with 10/100 Base-T standards and confirm that the single enable pin architecture fits the system logic requirements.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3L series of LAN switches produced by Diodes Incorporated (formerly Pericom). It serves as a high-speed electronic alternative to mechanical relays in local area network environments. The device is designed to multiplex differential outputs from PHY devices to corresponding outputs while maintaining low bit-to-bit skew and high channel-to-channel noise isolation.
