DS91D176TMA/NOPB

Overview

The DS91D176TMA/NOPB is a single-channel M-LVDS transceiver manufactured by Texas Instruments. It operates with a supply voltage range of 3 V to 3.6 V and supports data rates up to 200 Mb/s. The device accepts LVCMOS, LVTTL, or M-LVDS inputs and provides LVTTL or M-LVDS outputs. It functions within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a propagation delay of 7.5 ns, a maximum power dissipation of 833 mW, and a typical operating current of 29.5 mA at 3.3 V. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Supports multiple input logic standards including LVCMOS, LVTTL, and M-LVDS for flexible system integration.
• Provides configurable output options compatible with both LVTTL and M-LVDS signaling requirements.
• Operates reliably across the extended industrial temperature range from -40°C to +85°C.

Applications

• High-speed serial data transmission links requiring M-LVDS compliance
• Interface conversion between LVCMOS/LVTTL logic levels and M-LVDS differential lines
• Point-to-point communication channels in industrial equipment

Procurement Notes

Verify the complete part number including suffixes such as TMA and NOPB to ensure correct packaging and lead-free status. Confirm that the SOIC-8 package variant matches the target PCB footprint. Check RoHS compliance documentation for specific regulatory requirements. Ensure the operating voltage and temperature ranges align with the final application environment before ordering.

Selection Notes

Select this component when a single channel of M-LVDS transceivers is required alongside LVCMOS or LVTTL compatibility. Compare against the DS91C176 series if CML input support is needed instead of LVCMOS/LVTTL. Consider the DS91D180 if dual-channel functionality is necessary for the design. Evaluate power consumption constraints given the 29.5 mA operating current at 3.3 V.

Part Context

This device belongs to the DS91D176 family of low-voltage differential signaling interface ICs. It serves as a bridge between single-ended logic families and differential M-LVDS networks. The NOPB suffix indicates a lead-free and rohs-compliant manufacturing process. It is distinct from the DS91C176 which utilizes CML inputs rather than LVCMOS/LVTTL.

Replacement Considerations

The DS91D176TMAX/NOPB is a direct pin-compatible alternative within the same family. The DS91C176TMA/NOPB offers similar performance but requires CML input signals instead of LVCMOS or LVTTL. Designers must verify input signal compatibility when substituting these parts.
