PI5L200LEX

Overview

The PI5L200LEX is a rail-to-rail quad 2:1 multiplexer/demultiplexer LanSwitch manufactured by Diodes Incorporated. It operates from a single 3.3V or 5V supply and features three-state outputs. The device typically exhibits an on-resistance of 6 ohms at 5V and 5 ohms at 3.3V, with a maximum channel bandwidth of 137 MHz. Key electrical parameters include a typical quiescent supply current of 100 nA, off-isolation of -55 dB at 30 Mbps, and crosstalk of -70 dB at 30 Mbps. It supports data rates exceeding 135 Mbps and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail operation enables switching between different LAN signals in low voltage systems.
• High-performance design provides very low distortion and wide bandwidth for Fast Ethernet and ATM25 signals.
• Low power consumption achieved through minimal quiescent supply current.
• Replaces mechanical relays with a high-performance, low-cost solid-state solution.

Applications

• 10/100 Base-TX/T4 networks
• 100VG-AnyLAN systems
• Token Ring 4/16 Mbps interfaces
• ATM25 signal switching
• NIC Adapter and Hubs

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type corresponds to the L suffix for 16-pin TSSOP. Ensure the operating environment remains within the specified temperature range of -40°C to +85°C. Validate that the supply voltage matches the required 3.3V or 5V levels for proper functionality.

Selection Notes

Select this component when replacing mechanical relays in LAN applications requiring low distortion and high bandwidth. Ensure the design accommodates the 16-pin TSSOP package dimensions. Verify that the system logic levels are compatible with TTL interface requirements. Consider the low quiescent current benefit for power-sensitive designs.

Part Context

The PI5L200 series includes variants such as PI5L200WEX (SOIC) and PI5L200QEX (QSOP). The L suffix specifically denotes the 16-pin TSSOP package. All variants share identical electrical characteristics but differ in physical footprint and thermal properties.

Replacement Considerations

Direct substitutes include PI5L200WEX and PI5L200QEX. These parts offer identical electrical performance but utilize SOIC and QSOP packages respectively. Verify pin compatibility and board space constraints before substitution.
