IDT74FCT3807AQ

Clock Buffers, Drivers Overview

The IDT74FCT3807A is a 3.3V CMOS 1-to-10 clock driver built using advanced dual metal CMOS technology. It provides low skew clock distribution with guaranteed maximum skew of less than 350ps and very low duty cycle distortion under 350ps. The device features high-speed propagation delay of less than 3ns (max) at 50MHz, TTL compatible inputs and outputs, and low input capacitance of 4.5pF typical. It operates within a supply voltage range of 3.3V ± 0.3V and supports commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Clock Buffers, Drivers Feature Summary

• 1:10 fanout clock driver with low skew (< 350ps max) and low duty cycle distortion (< 350ps max)
• High speed performance with propagation delay < 3ns (max) and output rise/fall time < 1.5ns (max)
• TTL compatible inputs and outputs; inputs can be driven from 3.3V or 5V components
• Low input capacitance (4.5pF typical) with hysteresis for improved noise margins

Clock Buffers, Drivers Applications

• Clock distribution networks
• Signal distribution systems

Clock Buffers, Drivers Procurement Notes

Verify the specific package suffix (SO, PY, Q, etc.) and temperature grade (I for Industrial, blank for Commercial) when ordering. Confirm RoHS compliance status as non-green parts were subject to end-of-life notifications in 2010. Ensure the selected variant matches the required operating temperature range for the application environment.

Clock Buffers, Drivers Selection Notes

Select the IDT74FCT3807A for standard commercial applications (0°C to +70°C) or the IDT74FCT3807AI for industrial environments (-40°C to +85°C). Choose between SOIC, SSOP, or QSOP packages based on board space constraints. Verify that the load capacitance requirements do not exceed the specified limits for the desired frequency operation up to 100MHz.

Clock Buffers, Drivers Part Context

The IDT74FCT3807/A belongs to the FCT3807 family of 3.3V CMOS clock drivers. It was originally manufactured by Integrated Device Technology, Inc., which has since been acquired by Renesas Electronics Corporation. The device is part of the broader 74FCT logic series designed for high-speed digital applications requiring efficient clock distribution.

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin replacements may include other 1:10 clock drivers from the 74FCT family. Verify compatibility regarding propagation delay, skew specifications, and package dimensions. Check current manufacturer availability as original IDT parts may have reached end-of-life status.
