PI49FCT3807QEX

Clock Buffers, Drivers Overview

The PI49FCT3807QEX is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring one input and ten non-inverting outputs. It provides a 1:10 fanout with ultra-low skew of 0.35ns and a maximum propagation delay of 3.5ns at VCC = 3.3V ±10%. The device operates within an industrial temperature range of –40°C to +85°C and accepts TTL-compatible inputs while delivering CMOS outputs. Packaged in a 20-pin QSOP (150-mil wide), it supports low input capacitance and minimal duty cycle distortion for high-speed clock distribution.

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates potential discontinuation or lifecycle changes. Confirm that the 'Q' suffix corresponds to the 20-pin 150-mil QSOP package and the 'E' suffix denotes Pb-free and Green compliance. Ensure the ordering code matches the required speed grade and packaging format before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source requires driving up to ten loads with minimal skew. The 3.3V supply voltage and TTL-compatible input levels make it suitable for mixed-voltage logic interfaces. Verify that the 20-pin QSOP footprint fits the PCB layout constraints and that the thermal dissipation requirements are met within the specified operating temperature range.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT3807 series of 3.3V Fast CMOS clock drivers. The 'Q' suffix specifically identifies the 20-pin 150-mil wide QSOP package variant. Other variants include SSOP and SOIC packages with different speed grades designated by letters such as A, B, C, or D.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include other PI49FCT3807 variants with different packages (e.g., PI49FCT3807HEX for SSOP) or speed grades. Cross-brand equivalents should match the 1:10 fanout, 3.3V operation, and similar skew specifications.
