PI49FCT805TSE

Clock Buffers, Drivers Overview

The PI49FCT805TSE is a non-inverting Fast CMOS clock driver manufactured by Diodes Incorporated (formerly Pericom). It features two independent buffer groups, each driving five outputs from a standard TTL-compatible CMOS input. The device operates at VCC = 5.0V ± 5% with an industrial temperature range of -40°C to +85°C. Key electrical parameters include extremely low output skew (0.5ns typical), propagation delay of 1.5ns to 6.5ns (CL=50pF), and high impedance state control via active LOW Output Enable inputs.

Clock Buffers, Drivers Feature Summary

• Non-inverting clock driver with two independent 1-in, 5-out buffer banks
• Extremely low output skew: 0.5ns typical
• TTL input and CMOS output compatible
• Hysteresis on all inputs for noise immunity

Clock Buffers, Drivers Applications

• Clock distribution in synchronous systems
• High-speed data bus buffering
• Low skew clock routing for FPGAs or ASICs

Clock Buffers, Drivers Procurement Notes

Verify the 'E' suffix indicates Pb-free and Green packaging status as per manufacturer ordering information. Confirm the 'S' package code corresponds to the 20-pin 300-mil wide SOIC form factor. Ensure compatibility with 5.0V logic levels and check for required tape/reel options if an 'X' suffix is needed for automated assembly.

Clock Buffers, Drivers Selection Notes

Select this component when low skew (<0.7ns) and high drive capability are required for clock signals. Compare against PI49FCT2805TSE if lower noise via a 25-ohm on-chip resistor is necessary. Verify speed grade requirements; the base 'Blank' grade offers up to 6.5ns max propagation delay, while 'C' grade reduces this to 4.5ns.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. It is functionally similar to the PI49FCT805T but specified with the 'SE' suffix for lead-free environmental compliance and the 'S' suffix for the specific SOIC package variant.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements within the same family include PI49FCT805ATSE (Speed Grade A) and PI49FCT805CTSE (Speed Grade C) for tighter timing constraints. For noise-sensitive applications, consider the PI49FCT2805TSE which includes an integrated 25-ohm series resistor.
