PI49FCT807TQEX

Clock Buffers, Drivers Overview

The PI49FCT807TQEX is a Fast CMOS clock driver manufactured by Diodes Incorporated (formerly Pericom). It features one input and ten outputs, providing a 1:10 fanout. The device operates within an industrial temperature range of -40°C to +85°C and supports TTL inputs with CMOS outputs. Key electrical parameters include a maximum propagation delay of 3.5 ns for the C speed grade, a typical output high voltage of 3.3V at VCC=Min, and a quiescent power supply current of 33 µA. It is housed in a 20-pin QSOP package.

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates it is a legacy product from Pericom Semiconductor Corporation, now part of Diodes Incorporated. Confirm that the 'E' suffix denotes Pb-free and Green packaging, and the 'X' suffix indicates Tape/Reel packaging. Ensure compatibility with existing 20-pin QSOP footprints during sourcing.

Clock Buffers, Drivers Selection Notes

Select the PI49FCT807TQEX when a single clock source needs to drive up to ten loads with minimal skew. The C speed grade offers a maximum propagation delay of 3.5 ns. Ensure the design accommodates a 5.0V ±5% supply voltage and utilizes the 20-pin QSOP package dimensions provided in the mechanical drawings.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT807 family of fast CMOS clock drivers. Variants such as the CTQEX and TSEX share the same core functionality but differ in speed grades and specific packaging options. The Q suffix specifically identifies the 20-pin 150-mil wide QSOP package type.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same series include PI49FCT807CTQEX, which shares the QSOP package but has a guaranteed skew of 0.25ns compared to the standard grade.
