PI49FCT3805AQE

Clock Buffers, Drivers Overview

The PI49FCT3805AQE is a 3.3V non-inverting clock driver manufactured by Diodes Incorporated, belonging to the FCT series. It features two independent buffer groups with a 1-in, 5-out configuration per bank, providing eight true outputs and one monitor output. The device operates within an industrial temperature range of –40°C to +85°C and utilizes a 20-pin QSOP package. Key electrical parameters include a maximum propagation delay of 5.8 ns (Grade A), extremely low output skew of 0.7 ns, and typical quiescent power consumption of 1 mW. Inputs are TTL compatible with CMOS outputs.

Clock Buffers, Drivers Feature Summary

• Two independent 1-to-5 fanout buffer banks with active LOW 3-state Output Enable controls
• Extremely low output skew of 0.7 ns for high-speed clock distribution
• Dedicated MON pin provides a heartbeat signal identical to other outputs for diagnostics
• TTL input and CMOS output compatibility with hysteresis on all inputs

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring low skew
• PLL driving applications utilizing the monitor output
• Single point-to-point transmission line driving
• Address distribution systems

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'QE' corresponds to the Pb-free & Green 20-pin 150-mil QSOP package as specified in the datasheet. Confirm that the 'A' speed grade meets the required maximum propagation delay of 5.8 ns for the target application timing constraints.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting logic function is required. For inverting requirements, consider the PI49FCT3806. Ensure the load capacitance does not exceed 50 pF to maintain the specified switching characteristics. Verify that the 3.3V supply voltage aligns with the system's power rails.
