FIN1027K8X

Overview

The FIN1027K8X is a high-speed, differential line driver belonging to the Fairchild Semiconductor LVDS family. It integrates two independent drivers designed for low-voltage differential signaling applications. The device operates with a supply voltage range of 3.0 V to 3.6 V and supports data transmission rates up to 600 Mbps. It accepts LVTTL input signals and converts them into differential LVDS outputs. The component is housed in an 8-pin SOIC package with dimensions of 5 mm x 4 mm x 1.5 mm. It functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Supports high-speed differential signaling with data rates up to 600 Mbps
• Converts single-ended LVTTL inputs to differential LVDS outputs
• Operates on a single 3.3 V power supply rail

Applications

• High-speed serial communication interfaces
• Point-to-point differential signal transmission
• Data bus buffering and driving

Procurement Notes

Verify the manufacturer marking and date code against official distributor catalogs. Confirm the suffix K8X indicates tape and reel packaging. Ensure the component matches the 8-pin SOIC physical footprint. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when interfacing LVTTL logic sources with LVDS receivers. It is suitable for applications requiring moderate speed up to 600 Mbps. Consider thermal dissipation limits within the specified operating temperature range. Verify that the load capacitance requirements are met by the receiving end.

Part Context

This part is part of the FIN1027 series from Fairchild Semiconductor, now under ON Semiconductor. The series includes variants like FIN1027A and FIN1027AM. These devices are commonly used in systems requiring reliable differential data transmission over short to medium distances.

Replacement Considerations
