DS91C180TMAX

Overview

The DS91C180TMAX is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a dual M-LVDS line driver and receiver pair, supporting data rates up to 200 Mb/s. The device operates within a supply voltage range of 3 V to 3.6 V, with a typical operating current of 29.5 mA at 3.3 V. It features a propagation delay of 5.5 ns and dissipates approximately 1.1 W of power. Designed for surface-mount applications, it is housed in a 14-SOIC package and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports dual-channel M-LVDS transmission with LVCMOS/LVTTL input compatibility
• Provides high-speed data transfer capability up to 200 Mb/s
• Operates reliably across the extended industrial temperature range

Applications

• High-speed serial communication links requiring differential signaling
• Industrial control systems and automation interfaces
• Test and measurement equipment signal distribution

Procurement Notes

Verify the specific suffix configuration when ordering, as packaging and environmental compliance may vary between variants such as TMA and TMAX. Confirm RoHS status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure the selected package matches the intended PCB layout requirements for the SOIC-14 form factor.

Selection Notes

Select this component when a dual-channel LVDS transceiver is required for board-to-board or backplane connections. Consider the 14-pin SOIC footprint for space-constrained designs. Verify that the system power budget accommodates the specified 29.5 mA operating current and that the 200 Mb/s speed meets the application's bandwidth needs without requiring higher-performance alternatives.

Part Context

This part belongs to the DS91C/D series of LVDS interface devices from Texas Instruments. These components are designed to bridge single-ended logic levels to differential signaling standards, facilitating noise-immune data transmission over longer distances compared to traditional CMOS interfaces.

Replacement Considerations

The DS91D180TMA is a documented variant within the same family offering identical electrical specifications but potentially differing in packaging or environmental certification. Verify pinout compatibility and thermal characteristics before substituting.
