TS3L100DE4

Analog Switches - Special Purpose Overview

The TS3L100DE4 is a quad single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It features low on-state resistance and wide bandwidth, designed for LAN and POE applications. The device operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 15 Ohms and an operating supply current of 100 nA. It supports signal swings from ground to the positive rail. The component is housed in a 16-pin SOIC-Narrow package and functions reliably across an operating temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Quad SPDT architecture providing four independent signal paths
• Wide bandwidth capability suitable for high-speed data transmission
• Low power consumption with minimal operating supply current
• Rail-to-rail signal handling for flexible interface compatibility

Analog Switches - Special Purpose Applications

• LAN port protection and switching
• POE (Power over Ethernet) signal routing
• High-speed data line multiplexing
• Telecommunications equipment signal switching

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance as per Texas Instruments standards. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the datasheet revision to ensure parameter consistency.

Analog Switches - Special Purpose Selection Notes

Select this component when multiple independent SPDT switches are required in a compact form factor. Consider the 15 Ohm on-resistance limit for signal integrity requirements. Verify that the 0°C to +70°C commercial temperature range is sufficient for the deployment environment. Compare against other members of the TS3L100 family for package or pinout variations.

Analog Switches - Special Purpose Part Context

The TS3L100DE4 belongs to the TS3L100 series of analog switches from Texas Instruments. This series is optimized for broadband applications requiring low distortion and high isolation. The DE4 designation typically denotes a specific packaging and lead-free variant within the broader TS3L100 product line, sharing core electrical characteristics with other variants like the TS3L100DR or TS3L100PWG4.

Analog Switches - Special Purpose Replacement Considerations

Compatible substitutes include TS3L100DR and TS3L100PWG4. Verify pin compatibility and package dimensions before substitution. Ensure the alternative part meets the same on-resistance and bandwidth specifications.
