TS5L100DBQR

Overview

The TS5L100DBQR is a quad 1-of-2 multiplexer/demultiplexer manufactured by Texas Instruments in an SSOP package. It operates within a supply voltage range of 6 V to 6.5 V and supports data rates suitable for 10 Base-T and 100 Base-T signaling. The device features a minimum bandwidth of 300 MHz, a typical on-state resistance of 3 ohms, and low differential crosstalk of -60 dB. It includes an Ioff feature for partial-power-down mode operation and provides undershoot clamp diodes on data and control inputs.

Feature Summary

• Supports bidirectional data flow with near-zero propagation delay
• Enables partial-power-down mode via the Ioff feature to prevent backflow current
• Provides high isolation and low crosstalk for signal integrity in LAN applications

Applications

• 10 Base-T signaling networks
• 100 Base-T signaling networks
• LAN switch replacement for mechanical relays

Procurement Notes

Verify the specific ordering suffix DBQR corresponds to the SSOP tape and reel packaging configuration. Confirm that the operating environment remains within the specified 0°C to 70°C temperature range and that the supply voltage strictly adheres to the 6 V to 6.5 V limit to ensure proper functionality.

Selection Notes

Select this component when a wide bandwidth exceeding 300 MHz is required for LAN signal routing. Ensure the system design accommodates the narrow 6 V to 6.5 V supply voltage window. Verify that the SSOP package dimensions fit the available PCB space and that the thermal requirements are met for the intended application density.

Part Context

This part belongs to the TS5L100 family of LAN switches from Texas Instruments. It serves as a solid-state alternative to mechanical relays in network infrastructure. The family offers various package options including SOIC, TSSOP, and QFN, allowing designers to choose the form factor that best suits their manufacturing and spatial constraints.

Replacement Considerations

Direct substitutes include other parts within the TS5L100 family such as TS5L100D or TS5L100PWR, provided the package type matches the board layout. Cross-family replacements require verification of the 6 V to 6.5 V supply voltage compatibility and bandwidth specifications.
