PI49FCT3805AHE

Clock Buffers, Drivers Overview

The PI49FCT3805AHE is a 3.3V non-inverting clock driver manufactured by Diodes Incorporated (formerly Pericom). It features two independent buffer groups, each with a 1-in, 5-out configuration and active LOW 3-state Output Enable inputs. The device utilizes advanced CMOS technology to achieve extremely low output skew of 0.5ns maximum and very low duty cycle distortion under 1.0ns. It includes a dedicated monitor output pin for diagnostics and PLL driving. Electrical characteristics specify a propagation delay of 1.5ns to 5.8ns at VCC = 3.3V ± 0.3V. The component operates within an industrial temperature range of –40°C to +85°C and is housed in a 20-pin SSOP package.

Clock Buffers, Drivers Feature Summary

• Dual independent buffer banks with 1:5 fanout per group
• Extremely low output skew of 0.5ns maximum
• Dedicated MON output pin for system diagnostics
• TTL compatible inputs with hysteresis on all pins

Clock Buffers, Drivers Applications

• Clock distribution networks requiring low skew
• PLL driving applications
• System monitoring via heartbeat signals
• High-speed digital logic buffering

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'HE' confirms the Pb-free and Green status alongside the 20-pin 209-mil SSOP package code 'H'. Confirm the speed grade 'A' aligns with the required propagation delay specifications before procurement. Ensure compatibility with the 3.3V supply voltage range of 3.0V to 3.6V.

Clock Buffers, Drivers Selection Notes

Select this part for designs requiring non-inverting clock distribution with specific diagnostic capabilities. The 'A' speed grade offers a balance between speed and power consumption compared to faster grades. Consider the 209-mil SSOP package dimensions if board space allows for wider pitch compared to QSOP options.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT series of 3.3V Fast CMOS buffers. It is the non-inverting counterpart to the PI49FCT3806. The series is designed as a 3.3V version of legacy 5V devices like the PI49FCT805/806, maintaining pin compatibility while lowering power consumption.
