74FCT2244ZCTQ

Buffers, Drivers, Receivers, Transceivers Overview

The IDT 74FCT2244ZCTQ is an octal buffer and line driver belonging to the 74FCT logic family. It features eight non-inverting channels with three-state outputs, housed in a 20-pin QSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. It provides high-speed performance with a propagation delay of approximately 4.6 ns at 5 V, alongside low static current consumption of 100 nA. The component is designed for surface-mount installation and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZCTQ against the manufacturer's latest documentation to confirm pinout, package dimensions, and electrical characteristics. Confirm RoHS compliance status as historical data may vary by production batch. Ensure the source document explicitly identifies the manufacturer as IDT or Renesas Electronics to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for 5 V logic systems. It is suitable for designs needing high drive capability and fast switching speeds. Consider the QSOP package constraints for PCB layout. Verify that the application voltage remains strictly within the 4.75 V to 5.25 V range to ensure reliable operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FCT family of Fast CMOS logic devices manufactured by Integrated Device Technology (IDT), which has been acquired by Renesas Electronics.
