PI49FCT3804SE

Clock Buffers, Drivers Overview

The PI49FCT3804SE 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-to-4 output configuration controlled by active LOW Output Enable inputs (OEA, OEB). The device utilizes Fast CMOS technology to achieve low output skew of 0.7ns and extremely low static power consumption of 1mW typical. It accepts TTL-compatible CMOS inputs and provides outputs capable of driving standard TTL loads, reducing ground bounce issues.

Clock Buffers, Drivers Feature Summary

• Two independent 1-in, 4-out non-inverting buffer groups with Hi-Z state control via active LOW enable pins
• Low output skew of 0.7ns and propagation delay maximum of 6.5ns at 50pF load
• TTL input levels and CMOS output levels for compatibility and reduced ground bounce
• ESD protection exceeding 2000V and hysteresis on all inputs

Clock Buffers, Drivers Applications

• Clock distribution in high-speed digital systems
• Bus buffering for memory and peripheral interfaces
• Signal conditioning where low skew and low power are required

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates potential discontinuation or lifecycle changes for specific variants within the PI49FCT series. Confirm that the 'SE' suffix denotes Pb-free and Green packaging compliant with environmental standards. Ensure the selected package matches the 16-pin SOIC requirement for PCB layout integration.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting buffer with dual independent banks is required for 3.3V logic systems. It is suitable for replacing the older PI49FCT804T in new designs due to lower power consumption. Ensure the load capacitance does not exceed 50pF to maintain the specified timing parameters. Verify that the input voltage levels align with the guaranteed TTL HIGH/LOW thresholds provided in the DC characteristics.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. The series includes both inverting (PI49FCT3806) and non-inverting (PI49FCT3805/3804) drivers. The PI49FCT3804 specifically offers a 1-to-4 fanout per bank, distinguishing it from higher fanout variants like the PI49FCT3805 which provides 1-to-5 fanout.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3804S is the standard leaded version of this component. For direct pin-compatible replacement, verify if the legacy PI49FCT804T can be substituted, noting differences in supply voltage and power specifications.
