PI49FCT804ATS

Clock Buffers, Drivers Overview

The PI49FCT804ATS is a non-inverting clock driver manufactured by Diodes Incorporated, utilizing advanced 0.8 micron CMOS technology. It features two independent buffer groups, each with a 1-in, 4-out configuration and active LOW Hi-Z Output Enable inputs (OEA, OEB). The device operates at VCC = 5.0V ± 5% with TTL-compatible input levels. Key electrical parameters include low output skew of 0.8ns typ, high output drive capability (IOL = 64mA), and extremely low static power consumption (1mW typ). Propagation delays range from 0.65ns to 0.85ns depending on transition direction.

Clock Buffers, Drivers Feature Summary

• Two independent 1-to-4 non-inverting buffer groups with active LOW enable control
• Low output skew of 0.8ns typical for precise clock distribution
• TTL compatible input/output levels reducing ground bounce issues
• High output drive strength with IOL up to 64mA

Clock Buffers, Drivers Applications

• Clock busing systems requiring Hi-Z state control
• High-speed digital circuits needing low skew signal distribution
• Systems utilizing standard TTL compatible CMOS inputs

Clock Buffers, Drivers Procurement Notes

Verify the 'A' suffix in PI49FCT804ATS against official documentation to confirm specific package or temperature grade variations. Confirm RoHS compliance status as datasheet versions may vary. Check for end-of-life notifications or product change notices from Diodes Incorporated before finalizing procurement plans.

Clock Buffers, Drivers Selection Notes

Select this component when low skew clock distribution is critical. Ensure load capacitance requirements are met within the specified limits (CL=50pF test condition). Verify that the 16-pin QSOP or SOIC package fits the PCB layout constraints. Consider the 0.8ns skew performance for timing-sensitive applications compared to standard buffers.

Clock Buffers, Drivers Part Context

This part belongs to the Pericom PI49FCT series of logic circuits produced using 0.8 micron CMOS technology. The series is known for industry-leading speed grades. The PI49FCT804T variant specifically provides dual 1:4 buffering capabilities, distinguishing it from single-bank drivers or higher fan-out devices in the same family.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements within the PI49FCT804 family should be verified via official substitution lists. Generic FCT-series buffers may not match the specific 0.8ns skew or 64mA drive current specifications.
