Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix 'Z' against official manufacturer documentation, as it may indicate specific environmental compliance or packaging variations not universally standardized across all distributors. Confirm lead times and availability directly with authorized suppliers, as this specific variant may have limited stock compared to standard commercial grades.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with FCT speed performance and low power consumption is required. Ensure the design accommodates the 4.75 V to 5.25 V supply voltage range. Verify that the QSOP-20 package dimensions fit the PCB layout constraints and that thermal management meets the -40°C to +85°C operational requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT2244T series of octal buffers. It shares functional similarities with other FCT family members like the 74FCT244 but offers specific drive current characteristics optimized for reducing switching noise. It is designed for applications requiring high-speed data transfer with minimal power dissipation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the CY74FCT2244 series from Texas Instruments and the PI74FCT2244 series from Pericom/Diodes Incorporated. These alternatives share the same logical function and pinout but require verification of electrical parameters such as propagation delay and drive strength.
