DS91M047TMAX/NOPB

Overview

The DS91M047TMAX/NOPB is a quad M-LVDS line driver manufactured by Texas Instruments, operating within a supply voltage range of 3 V to 3.6 V at a nominal 3.3 V. It supports data rates up to 250 Mb/s with an input type of LVCMOS or LVTTL and outputs M-LVDS signals. The device features four drivers and four receivers, housed in a 16-pin SOIC package. It operates between -40°C and +85°C, draws 75 mA typically, dissipates 2.21 W, and has a propagation delay of 5 ns.

Feature Summary

• Provides four independent high-speed differential output channels for signal distribution.
• Accepts single-ended CMOS or TTL inputs and converts them to compliant M-LVDS differential signals.
• Designed for low power consumption relative to standard LVDS solutions while maintaining high data integrity.

Applications

• Clock distribution networks requiring fan-out buffering.
• High-speed serial data transmission interfaces.
• Point-to-multipoint signal routing in industrial equipment.

Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package matches the 16-SOIC specification and check the temperature grade against system requirements.

Selection Notes

Select this component when a quad channel M-LVDS driver is required for converting single-ended logic levels to differential signals. Compare against the DS90LV047ATMX if standard LVDS output is needed instead of M-LVDS. Verify that the 250 Mb/s speed meets the application bandwidth needs.

Part Context

This part belongs to the DS91M series of M-LVDS interface devices from Texas Instruments. It serves as a bridge between standard digital logic and low-voltage differential signaling standards, facilitating reliable communication over longer traces or noisy environments compared to single-ended signaling.

Replacement Considerations

The DS91M047TMA/NOPB is a tube-packaged variant of the same functional device. For standard LVDS output instead of M-LVDS, consider the DS90LV047ATMX/NOPB. Other family members include the DS91M125 for repeater functions.
