TS5L100PWR

Overview

The TS5L100PWR is a quad 1-of-2 multiplexer/demultiplexer switch manufactured by Texas Instruments in a TSSOP-20 package. It operates within a supply voltage range of 6 V to 6.5 V and supports an operating temperature from 0°C to 70°C. Key electrical parameters include a maximum on-resistance (ron) of 19 Ω for M1 channels and 6 Ω for M2 channels, with typical values of 11.2 Ω and 3 Ω respectively at VCC = 6.2 V. The device features a minimum bandwidth of 300 MHz, low differential crosstalk of -60 dB typ, and a maximum supply current of 3 µA. It includes Ioff support for partial-power-down mode and latch-up performance exceeding 100 mA per JESD 78 Class II.

Feature Summary

• Supports bidirectional data flow with near-zero propagation delay
• Enables partial-power-down operation via Ioff feature to prevent backflow current
• Provides undershoot clamp diodes on data and control inputs

Applications

• 10 Base-T signaling applications
• 100 Base-T signaling applications
• Replacing mechanical relays in LAN environments

Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-20 tape and reel packaging configuration. Confirm that the design requires the specified 6 V to 6.5 V supply voltage range rather than standard 3.3 V logic levels. Ensure the application environment remains within the 0°C to 70°C operating temperature limits defined for this part number.

Selection Notes

Select this component when high bandwidth and low crosstalk are required for LAN signal routing. The narrow 6 V to 6.5 V supply range distinguishes it from lower-voltage switches. Verify that the TSSOP-20 footprint fits the PCB layout constraints. Consider the Ioff capability if the system requires safe isolation during power-down states.

Part Context

The TS5L100PWR belongs to the TS5L100 series of LAN switches. It shares functional characteristics with variants like TS5L100DR and TS5L100DBQR, differing primarily in package type and shipping quantity. All variants maintain the same electrical specifications and pinout compatibility for the core switching functions.

Replacement Considerations

Direct replacements include TS5L100DR (SOIC-16) and TS5L100DBQR (SSOP-16). These parts share identical electrical performance but require different footprints. Verify board space and soldering process compatibility before substituting.
