TS5L100D

Overview

The TS5L100D is a four-channel 1-of-2 multiplexer/demultiplexer switch manufactured by Texas Instruments in a 16-pin SOIC package. It operates within a supply voltage range of 6 V to 6.5 V and supports an operating temperature range of 0°C to 70°C. The device features a typical on-state resistance (ron) of 3 Ω, with a maximum of 19 Ω for M1 channels and 6 Ω for M2 channels at 4.5 V input. It provides a minimum bandwidth of 300 MHz and exhibits low differential crosstalk of -60 dB typ. Control inputs include a single enable pin (E) and a select pin (S).

Feature Summary

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

Applications

• 10 Base-T signaling networks
• 100 Base-T signaling networks
• LAN applications requiring relay replacement

Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the tube packaging format containing 40 units per tube. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure the selected part matches the required thermal impedance specifications for the intended PCB layout design.

Selection Notes

Select this component when a 6 V to 6.5 V supply rail is available for the analog switch operation. The 16-pin SOIC package is suitable for surface-mount assembly where standard spacing constraints apply. Consider the 300 MHz bandwidth requirement for high-frequency LAN signal routing needs.

Part Context

This device belongs to the TS5L100 family of LAN switches designed for Ethernet applications. The 'D' suffix specifically denotes the SOIC package variant, distinguishing it from SSOP or TSSOP options within the same functional series. It serves as a solid-state alternative to mechanical relays in network infrastructure.

FAQ

How does the Ioff feature function during power-down?

The Ioff feature ensures that damaging current will not backflow through the device when it is powered down, providing isolation during the power-off state.

What is the recommended method to ensure high-impedance state during power cycles?

To ensure the high-impedance state during power up or power down, the Enable (E) input should be tied to VCC through a pullup resistor.
