FIN1531M

Overview

The FIN1531M is a quad high-speed differential driver designed for Low Voltage Differential Signaling (LVDS) applications. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 16-SOIC package. The device provides four independent LVDS drivers, enabling efficient data transmission over high-speed interconnects. It supports CMOS and TTL logic levels at the input, ensuring compatibility with standard digital interfaces while delivering the low-voltage swing characteristics required for LVDS receivers.

Feature Summary

• Provides four independent LVDS driver channels for high-speed data transmission
• Compatible with CMOS and TTL input logic levels
• Designed specifically for low-voltage differential signaling interconnects

Applications

• High-speed serial data links
• Point-to-point interconnects requiring LVDS standards
• Digital interface circuits utilizing differential signaling

Procurement Notes

Verify the manufacturer marking and date code against Fairchild Semiconductor specifications. Confirm the 16-SOIC package type and pinout alignment. Ensure the component matches the active status and electrical parameters defined in the official datasheet before integration into production designs.

Selection Notes

Select this component when designing systems requiring multiple LVDS outputs from a single source. It is suitable for applications needing direct CMOS/TTL interfacing without additional level shifting. Consider the thermal performance and board space requirements associated with the SOIC-16 package during layout planning.

Part Context

This part belongs to the family of LVDS transmitters manufactured by Fairchild Semiconductor, now part of onsemi. It serves as a key interface solution for converting parallel or serial digital signals into differential pairs for noise-immune transmission. The FIN1531M complements other LVDS receivers and drivers in system-level communication architectures.

Replacement Considerations

The FIN1531MX is a documented variant within the same product line. Verify pin compatibility and electrical specifications before substituting.
