49FCT805BTSOG8

Overview

The 49FCT805BTSOG8 is a dual clock driver and distribution buffer manufactured by Renesas Electronics. It operates on a single 5V supply voltage, with a minimum operating voltage of 5V. The device features a 1:5 multiplication or division factor for each of its two independent circuits. It supports CMOS, LVCMOS, and TTL output types, driven by an LVCMOS input type. The maximum output frequency reaches 166 MHz. Designed for surface mount installation, it is housed in a 20-SOIC package. The component functions within a commercial temperature range from 0°C to +70°C.

Feature Summary

• Dual circuit architecture providing two independent 1:5 clock drivers
• Supports CMOS, LVCMOS, and TTL output logic levels
• Maximum operating frequency of 166 MHz
• Housed in a 20-SOIC surface-mount package

Applications

• Clock signal distribution in digital systems
• Buffering and driving high-capacitance loads
• Timing synchronization in data communication equipment

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be discontinued or subject to limited availability. Confirm that the 20-SOIC package dimensions match the target PCB footprint. Ensure the 5V supply voltage aligns with the system design requirements. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a dual-channel clock buffer with mixed logic level support (CMOS/LVCMOS/TTL) is required. The 166 MHz maximum frequency suits moderate-speed timing applications. Verify that the 5V operating voltage matches the system power rails. Consider the 20-SOIC package size for board space constraints compared to other available packages in the 49FCT805 series.

Part Context

This part belongs to the 49FCT805T series of Fast CMOS clock drivers. It is functionally related to variants such as the 49FCT805BTSOG and 49FCT805PYG8, which share similar electrical characteristics but differ in packaging or specific output configurations. The 'BTSOG8' suffix typically denotes the SOIC-20 tube packaging variant within the Renesas product line.
