PI49FCT805TQE

Clock Buffers, Drivers Overview

The PI49FCT805TQE is a non-inverting Fast CMOS clock driver manufactured by Diodes Incorporated (formerly Pericom). It features two independent buffer groups, each providing five outputs from a single TTL-compatible CMOS input. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 20-pin QSOP package with a 150-mil width. Key electrical characteristics include a maximum propagation delay of 6.5 ns at VCC = 5.0V ± 5% and an extremely low output skew of 0.7 ns. The circuit supports Hi-Z 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 of 0.5 ns typical and 0.7 ns maximum
• TTL input and CMOS output compatibility with hysteresis on all inputs
• Low static power consumption with a typical quiescent current of 33 µA

Clock Buffers, Drivers Applications

• Clock distribution in high-speed digital systems
• Bus busing applications requiring Hi-Z state control
• Monitor output pin integration for signal integrity verification

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'Q' confirms the 20-pin 150-mil wide QSOP package. Confirm the 'E' suffix indicates Pb-free and Green compliant manufacturing. Ensure the speed grade corresponds to the required performance specifications for the target application environment.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting clock buffer with dual independent banks is required. The PI49FCT805TQE is suitable for designs needing TTL-compatible inputs driving CMOS loads. Consider the PI49FCT2805T variant if an integrated 25-ohm on-chip resistor for noise reduction is necessary instead of external termination.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of logic circuits produced using advanced submicron CMOS technology. The manufacturer transitioned from Pericom Semiconductor Corporation to Diodes Incorporated. The device is designed for industrial operation and offers industry-leading speed grades compared to standard FCT logic families.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT2805TQE serves as a functional alternative within the same package, featuring an integrated 25-ohm on-chip resistor. Other speed grades such as PI49FCT805ATQE or PI49FCT805BTQE offer improved propagation delays but must be verified against specific timing requirements.
