PI49FCT3807AHE

Clock Buffers, Drivers Overview

The PI49FCT3807AHE is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring one input and ten outputs with a 1:10 fanout configuration. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The device provides ultra-low skew of 0.35ns typical and propagation delays between 1.5ns and 4.5ns at VCC=3.3V with CL=15pF. It utilizes a 20-pin SSOP package (code H) and is compatible with TTL inputs and CMOS outputs.

Clock Buffers, Drivers Feature Summary

• 1-to-10 clock fanout with ultra-low skew of 0.35ns typical
• TTL input and CMOS output compatibility
• Low input capacitance (max 6.0 pF)
• Industrial temperature operation (-40°C to +85°C)

Clock Buffers, Drivers Applications

• Clock distribution networks
• Signal distribution systems
• High-speed digital circuit buffering

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'HE' corresponds to the 20-pin 209-mil wide SSOP package in tape-and-reel format. Confirm RoHS compliance status as the datasheet indicates Pb-free and Green availability for this series. Check for any specific PCN notifications regarding manufacturing site changes or material substitutions before finalizing procurement.

Clock Buffers, Drivers Selection Notes

Select the PI49FCT3807AHE when a single-ended 1:10 non-inverting clock buffer is required. Ensure the design load capacitance does not exceed 15pF to maintain the specified maximum propagation delay of 4.5ns. Verify that the system power supply remains within the 3.0V to 3.6V range for optimal performance and noise margin.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT3807 series of 3.3V Fast CMOS clock drivers. The 'A' suffix denotes a specific speed grade, while 'H' specifies the SSOP package type. It serves as a low-skew alternative to older FCT series devices, designed for high-speed clock distribution applications requiring minimal duty cycle distortion.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements within the same series include PI49FCT3807BHEX, PI49FCT3807CHEX, and PI49FCT3807DHEX, which offer different speed grades. Cross-package equivalents are available in QSOP (Q) and SOIC (S) formats, such as PI49FCT3807AQEX and PI49FCT3807ASEX, provided the footprint allows.
