PI49FCT3807ASEX

Clock Buffers, Drivers Overview

The PI49FCT3807ASEX is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring a 1-to-10 fanout configuration with one input and ten outputs. 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 provides ultra-low skew of 0.35ns typ and propagation delays between 1.5ns and 3.5ns max at VCC=3.3V. It accepts TTL-compatible inputs and delivers CMOS outputs, ensuring low noise levels and minimal duty cycle distortion for clock distribution applications.

Clock Buffers, Drivers Feature Summary

• 1:10 fanout clock driver with ultra-low skew (0.35ns typ) and high-speed propagation delay (max 3.5ns).
• TTL input and CMOS output compatibility with VOH = 3.3V (typ) and VOL = 0.3V (typ).
• Low input capacitance (max 6.0pF) and minimum duty cycle distortion.
• Industrial temperature operation from –40°C to +85°C with 3.3V ±10% supply voltage.

Clock Buffers, Drivers Applications

• Clock and signal distribution systems.
• High-speed digital circuits requiring low skew buffering.
• Systems utilizing TTL inputs with CMOS output requirements.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'ASEX' corresponds to the specific speed grade 'A' and tape/reel packaging in the 20-pin SOIC format. Confirm RoHS3 compliance and green status as indicated by the 'E' and 'X' suffixes. Check for any product change notifications or end-of-life statuses directly from the manufacturer before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 non-inverting clock buffer is required with strict skew specifications. Ensure the application voltage matches the 3.3V nominal supply. Consider the propagation delay limits (1.5ns to 3.5ns) against system timing requirements. Verify that the 20-pin SOIC package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of 3.3V Fast CMOS logic circuits produced using advanced submicron CMOS technology. It is a variant of the PI49FCT807, specifically optimized for 3.3V operation. The 'A' suffix denotes a specific speed grade, while 'SEX' indicates the 20-pin SOIC package with tape/reel packaging.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include other speed grades of the same family such as PI49FCT3807BSEX or PI49FCT3807DSEX, which offer different propagation delay characteristics but maintain the same pinout and functionality. Ensure the replacement part's speed grade meets the system's timing requirements.
