IDT74FCT3807ASOI

Clock Buffers, Drivers Overview

The IDT74FCT3807ASOI is a 3.3V CMOS 1-to-10 clock driver manufactured by Renesas Electronics Corporation (formerly IDT). It utilizes advanced dual metal CMOS technology to provide low skew clock distribution with a maximum skew of 0.35ns. The device features TTL-compatible inputs and outputs, high-speed propagation delay under 3ns, and low input capacitance of 4.5pF typical. Designed for commercial temperature ranges (0°C to +70°C), it operates at VCC = 3.3V ± 0.3V and is housed in a 20-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• 1:10 fanout clock driver with guaranteed low skew < 350ps (max.)
• High speed performance with propagation delay < 3ns (max.)
• TTL compatible inputs and outputs with hysteresis for improved noise margins
• Low power consumption with very low CMOS power levels

Clock Buffers, Drivers Applications

• Clock signal distribution networks
• Signal distribution in high-speed digital systems
• Reducing loading on preceding drivers in complex circuitry

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'SOI' corresponds to the SOIC package and Industrial temperature range (-40°C to +85°C) if required, as datasheet lists Commercial (0°C to +70°C) for standard variants. Confirm RoHS compliance status as non-green parts faced EOL notifications historically. Check current availability as legacy components may have limited stock or require alternative sourcing strategies.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended clock source requires expansion to ten outputs with minimal skew. Ensure the system operates within the 3.3V supply voltage range. Verify that the load capacitance requirements align with the specified switching characteristics (e.g., CL = 10pF, 30pF, or 50pF) to maintain timing integrity. Consider thermal management for industrial temperature applications if ambient conditions exceed commercial limits.

Clock Buffers, Drivers Part Context

This part belongs to the FCT3807/A family of 3.3V CMOS clock drivers. It is functionally equivalent to other variants in the series differing primarily in package type (SSOP, QSOP) or temperature grade. The 'A' designation typically indicates specific electrical parameter optimizations compared to the base model.

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin replacements include other FCT3807 variants such as IDT74FCT3807SOG8 (SSOP) or IDT74FCT3807QGI (QSOP) provided temperature grades match. Cross-reference with Renesas or IDT official substitution guides for end-of-life transitions.
