DS90C031BTM

Overview

The DS90C031BTM is a low-voltage differential signaling (LVDS) quad CMOS differential line receiver manufactured by National Semiconductor. It accepts LVDS or TTL/CMOS compatible inputs and converts them to standard LVDS outputs, facilitating high-speed data transmission over twisted-pair cables. The device operates within a supply voltage range of 2.97V to 3.63V and supports data rates up to 65Mbps. It is housed in a 16-pin TSSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent differential receivers for parallel data processing
• Supports both LVDS and TTL/CMOS input signal compatibility
• Designed for low power consumption and reduced electromagnetic interference

Applications

• Flat panel display interfaces
• High-speed data acquisition systems
• Medical imaging equipment

Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired National Semiconductor's logic and interface product lines. Confirm that the specific part number corresponds to the original National Semiconductor manufacturing era if vintage sourcing is required, ensuring the component matches the specified electrical characteristics and package dimensions.

Selection Notes

Select this component when a quad-channel receiver is needed to convert single-ended signals to differential LVDS formats. Ensure the system design accommodates the 3.3V nominal supply voltage and verify that the 65Mbps maximum data rate meets the application's bandwidth requirements without requiring additional buffering.

Part Context

This device belongs to the DS90C series of LVDS interface components designed for video and data transmission applications. It serves as the receiving counterpart to drivers like the DS90C030, enabling point-to-point or multi-drop connections in digital video architectures where signal integrity over long distances is critical.

Replacement Considerations

The DS90C031BM/NOPB is a verified equivalent offering lead-free construction with identical pinout and functionality. Other potential replacements include the DS90C031MTX/NOPB, which shares the same core specifications but utilizes a different surface-mount package variant.
