TS3L100DBQR

Analog Switches - Special Purpose Overview

The TS3L100DBQR is a quad single-pole double-throw (SPDT) wide bandwidth LAN switch manufactured by Texas Instruments. It integrates four independent analog switches within a single 16-pin SSOP package, designed for low on-state resistance and high signal integrity in data communication applications. The device operates with a supply voltage of 3.3 V and maintains an operating temperature range from 0°C to +70°C. Key electrical specifications include a maximum on-resistance of 15 Ohms and a typical off-isolation of 42 dB. The component draws a quiescent supply current of 100 nA, ensuring minimal power consumption during standby modes while supporting surface-mount installation techniques.

Analog Switches - Special Purpose Feature Summary

• Integrates four independent SPDT analog switches for compact signal routing
• Optimized for wide bandwidth performance in LAN and POE applications
• Features low on-state resistance to minimize signal attenuation
• Provides high off-isolation to prevent crosstalk between channels

Analog Switches - Special Purpose Applications

• Power over Ethernet (PoE) interface circuits
• Local Area Network (LAN) signal switching
• Data line protection and multiplexing
• Telecommunications equipment signal routing

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix DBQR against official manufacturer documentation to confirm the SSOP-16 package type and tape-and-reel packaging configuration. Ensure that the industrial temperature grade and 3.3 V supply requirements align with the target system design before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when a quad SPDT configuration is required for LAN or PoE applications. Compare the 15 Ohm on-resistance and 42 dB isolation against alternative switches if higher bandwidth or lower resistance is needed. Confirm that the 16-pin SSOP footprint matches the PCB layout constraints and that the 0°C to +70°C temperature range meets environmental specifications.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3L100 series of wide bandwidth LAN switches. It shares functional similarities with other members of the family but differs in package style and suffix designation. The TS3L100 series is distinct from video switch variants like the TS3V330, which are optimized for different frequency ranges and voltage supplies.
