PI49FCT3804ASE

Clock Buffers, Drivers Overview

The PI49FCT3804ASE is a non-inverting clock driver manufactured by Diodes Incorporated, operating at 3.3V with an industrial temperature range of –40°C to +85°C. It features two independent buffer groups, each providing a 1-in, 4-out configuration with active LOW Hi-Z state Output Enable inputs. The device utilizes TTL-compatible CMOS input levels and delivers low output skew of 0.7ns typical. Electrical characteristics include a maximum propagation delay of 5.8ns (CL=50pF) and extremely low static power consumption of 1mW typical.

Clock Buffers, Drivers Feature Summary

• Two independent buffer groups with 1-in, 4-out non-inverting configuration
• Low output skew of 0.7ns typical for clock distribution applications
• TTL input and CMOS output compatibility reducing ground bounce issues
• Active LOW Output Enable inputs providing Hi-Z state control

Clock Buffers, Drivers Applications

• Clock bus distribution in high-speed digital systems
• Buffering clock signals between TTL and CMOS logic domains
• Fan-out buffering for multiple synchronous loads

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'ASE' corresponds to the Pb-free and Green compliant package variant as specified in the manufacturer's ordering information. Confirm the SOIC-16 package dimensions match the design footprint requirements before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting buffer with two independent 1-to-4 fan-out channels is required. Ensure the load capacitance does not exceed 50pF to maintain the specified 5.8ns maximum propagation delay. Verify that the 3.3V supply voltage aligns with the system power architecture.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. It serves as the 3.3V version of the legacy PI49FCT804T, offering improved speed grades and lower power consumption while maintaining pinout compatibility for system upgrades.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3804S is the standard leaded equivalent. For direct replacement, ensure the substitute supports the same 16-pin SOIC package and 3.3V operation. Verify that any alternative device meets the 0.7ns skew requirement if timing integrity is critical.
