DS91C180TMA/NOPB

Overview

The DS91C180TMA/NOPB is an LVDS interface integrated circuit manufactured by Texas Instruments, originally from the National Semiconductor portfolio. It functions as a dual M-LVDS line driver and receiver pair capable of data rates up to 200 Mb/s. The device operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. It accepts LVCMOS or LVTTL inputs and provides M-LVDS outputs. Key electrical parameters include a propagation delay of 5.5 ns, a maximum power dissipation of 1.1 W, and a quiescent current of 29.5 mA. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports dual independent M-LVDS differential signaling channels for high-speed data transmission.
• Provides compatibility with standard digital logic levels through LVCMOS and LVTTL input interfaces.
• Designed for low power consumption suitable for battery-operated or thermally constrained systems.

Applications

• Clock distribution networks in telecommunications equipment.
• Data acquisition systems requiring reliable differential signaling.
• Industrial control systems utilizing ATCA compliant architectures.

Procurement Notes

Verify the manufacturer designation carefully, as the component originates from National Semiconductor but is now distributed under the Texas Instruments brand. Confirm that the specific suffix /NOPB indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required PCB footprint, specifically the 14-SOIC variant. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a dual-channel M-LVDS transceiver is required for interfacing between LVCMOS/LVTTL sources and M-LVDS receivers. It is appropriate for applications needing 200 Mb/s throughput with minimal propagation delay. Consider the 14-pin SOIC package constraints and thermal dissipation limits of 1.1 W during system design. Evaluate if the single 3.3 V supply requirement aligns with the target board's power architecture.

Part Context

This part belongs to the DS91C180 series of M-LVDS drivers and receivers. It serves as a bridge between parallel digital buses and serial differential links. The device is often used in conjunction with other members of the DS91 family, such as repeaters or single-channel variants, to build complete communication subsystems. Its design facilitates noise immunity in electrically noisy environments typical of industrial and telecom settings.

Replacement Considerations

The DS91D180TMA/NOPB is a functionally similar device within the same family, offering identical electrical characteristics and pinouts. Verify that any substitute maintains the same M-LVDS output standards and input voltage tolerances. Ensure the replacement package remains compatible with the existing assembly process.
