IDT74FCT3807QI

Clock Buffers, Drivers Overview

The IDT74FCT3807QI is a commercial temperature range (0°C to +70°C) 3.3V CMOS 1-to-10 clock driver manufactured by Renesas Electronics Corporation, formerly Integrated Device Technology (IDT). It utilizes advanced dual metal CMOS technology to provide low skew and high-speed performance with a maximum propagation delay of 3ns at 50Ω AC termination. The device features TTL-compatible inputs and outputs, offering a 1:10 fanout ratio from a single input to ten outputs. It operates within a supply voltage range of 3.0V to 3.6V and includes hysteresis on inputs for improved noise margins.

Clock Buffers, Drivers Procurement Notes

Verify the package type suffix 'Q' corresponds to QSOP (Quarter-size Small Outline Package) as per the ordering information table. Confirm that the component meets the commercial temperature range specification of 0°C to +70°C. Check for RoHS compliance status, noting that non-green parts were subject to end-of-life notices in 2010.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended clock signal requires expansion into ten distinct paths with minimal timing skew. Ensure the system operates within the 3.3V ± 0.3V supply voltage range. Verify that the load capacitance requirements align with the specified switching characteristics for the desired frequency operation up to 100MHz.

Clock Buffers, Drivers Part Context

This part belongs to the FCT3807/A series of 3.3V CMOS clock drivers. The 'A' variant typically denotes specific speed or electrical characteristic improvements over the base model. The manufacturer transitioned from IDT to Renesas Electronics Corporation, which may affect documentation sources but not the underlying silicon specifications.

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin replacements include other variants within the 74FCT3807 family such as the industrial temperature version (IDT74FCT3807IQI) if wider temperature tolerance is required. Cross-manufacturer equivalents should be evaluated based on matching skew, propagation delay, and output drive current specifications.
