DS90C032TM

Overview

The DS90C032TM is a low-voltage differential signaling (LVDS) quad CMOS differential line receiver manufactured by National Semiconductor. It accepts LVDS inputs and converts them to TTL outputs, supporting data rates up to 155.5 Mb/s. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 10 mA. It features a propagation delay of 5 ns and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a 16-pin SOIC format, it is designed for high-speed serial data transmission applications requiring robust signal integrity.

Feature Summary

• Converts differential LVDS signals to single-ended TTL logic levels
• Supports high-speed data transmission at rates up to 155.5 Mb/s
• Provides four independent receiver channels in a compact package

Applications

• High-speed serial data communication links
• Video display interfaces and graphics systems
• Industrial control networks requiring noise immunity

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS requirements if applicable to your assembly process. Cross-reference the datasheet revision date to confirm the version matches your design constraints before finalizing procurement orders.

Selection Notes

Select this component when interfacing LVDS sources with TTL-compatible loads. Verify that the system power supply remains stable between 4.5 V and 5.5 V. Consider the 16-SOIC package dimensions for PCB layout constraints. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for reliable performance.

Part Context

This part belongs to the DS90C032 family of LVDS receivers. It serves as a bridge between differential transmission lines and standard digital logic circuits. The TM suffix typically denotes a specific tape-and-reel packaging variant or thermal grade within the National Semiconductor product line, distinct from other suffixes like BTMX or NOPB which may indicate different packaging or compliance standards.

Replacement Considerations

The DS90C032BTMX/NOPB is a documented equivalent offering identical functionality with updated manufacturing sourcing. Verify pin-to-pin compatibility and ensure the replacement supports the required 155.5 Mb/s data rate and 5V operation.
