PI49FCT3805AHEX

Clock Buffers, Drivers Overview

The PI49FCT3805AHEX is a 3.3V non-inverting clock driver manufactured by Diodes Incorporated, featuring two independent buffer groups with a 1-in, 5-out configuration per group. 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 utilizes a 20-pin SSOP package (H) with an 'E' suffix indicating Pb-free and Green compliance. Key electrical parameters include a maximum propagation delay of 5.8ns at CL=50pF, extremely low output skew of 0.7ps, and typical static power consumption of 1mW.

Clock Buffers, Drivers Feature Summary

• Two independent 1-to-5 non-inverting buffer groups with active LOW 3-state Output Enable inputs
• Extremely low output skew: 0.7ps (tSK(o)) between outputs of the same package
• TTL input and CMOS output compatibility with hysteresis on all inputs
• Pb-free and Green compliant packaging in a 20-pin 209-mil wide SSOP

Clock Buffers, Drivers Applications

• Clock distribution networks requiring low skew performance
• Bus systems utilizing 3-state control for clock gating
• Industrial applications operating within -40°C to +85°C environments

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'HEX' aligns with the manufacturer's standard 'HE' designation for Pb-free and Green 20-pin SSOP packages, as datasheet tables list 'HE'. Confirm the 'X' suffix does not indicate a specific tape-and-reel or custom variant not explicitly detailed in the provided documentation. Ensure the component meets RoHS3 and REACH requirements as stated for the base series.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting clock driver with 10 total outputs is required. Compare speed grades; the 'A' grade offers a max propagation delay of 5.8ns, which is faster than the commercial grade but slower than the B and C grades. Ensure the design accommodates the 20-pin SSOP footprint and that the load capacitance does not exceed 50pF for guaranteed timing specifications.

Clock Buffers, Drivers Part Context

The PI49FCT3805 belongs to the Pericom Semiconductor PI49FCT series, now produced by Diodes Incorporated. It is the non-inverting counterpart to the PI49FCT3806. The device is part of a family offering various speed grades (Blank, A, B, C) and packages (SOIC, QSOP, SSOP). The 'A' grade represents a specific performance tier within this fast CMOS logic line.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility if considering alternatives from other manufacturers, specifically regarding the MON pin and dual VCC/GND configurations.
