PI49FCT805ATQE

Clock Buffers, Drivers Overview

The PI49FCT805ATQE is a non-inverting clock driver manufactured by Diodes Incorporated, housed in a 20-pin QSOP package. It comprises two independent driver banks, each providing five outputs from TTL-compatible CMOS inputs. The device features extremely low output skew of 0.5ns and includes a monitor output pin for performance verification. Electrical characteristics specify a maximum propagation delay of 5.8ns at CL=50pF. Operating voltage ranges from 4.75V to 5.25V, with an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Two-driver architecture with five outputs per bank
• Extremely low output skew (0.5ns typical)
• TTL input and CMOS output compatibility
• Monitor output pin for signal integrity verification

Clock Buffers, Drivers Applications

• Clock distribution networks
• High-speed digital systems requiring low skew
• Synchronous logic circuits

Clock Buffers, Drivers Procurement Notes

Verify the 'A' speed grade suffix corresponds to the required 5.8ns maximum propagation delay specification. Confirm the 'Q' package code matches the 150-mil wide QSOP footprint requirements. Ensure the 'E' suffix indicates Pb-free and Green compliance if environmental standards are mandatory for the assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when low propagation delay and minimal skew are critical for timing alignment across multiple loads. The dual-bank design allows for separate clock domain management within a single package. Verify that the 50pF load capacitance requirement aligns with the target circuit design to ensure the specified switching characteristics are met.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT805 family of fast CMOS clock drivers. The 'A' suffix denotes a specific speed grade distinct from the standard, 'B', and 'C' variants found in the same series. It shares the same pinout and functional description as other speed grades but offers optimized switching performance parameters.

Clock Buffers, Drivers Replacement Considerations

PI49FCT805TQE serves as a baseline replacement with different speed characteristics. PI49FCT805BTQE and PI49FCT805CTQE offer faster propagation delays. All variants maintain identical pin configurations and packaging.
