Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer source, as IDT assets were acquired by Renesas Electronics. Confirm the part status regarding availability or end-of-life notifications. Ensure the datasheet matches the exact suffix requirements for the QSOP-20 package. Cross-reference electrical specifications with current official documentation to ensure compliance with design requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for 5V CMOS systems. It is appropriate for designs needing high drive strength and fast switching speeds. Consider the QSOP-20 package constraints for PCB layout. Verify that the input logic levels are compatible with the system's TTL-compatible signals.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader 74FCT family of high-speed CMOS logic devices. Similar parts include the CY74FCT244ATQCT from Texas Instruments and the PI74FCT244ATQE from Diodes Incorporated. These devices share similar functional characteristics but may differ in packaging options, speed grades, or specific electrical parameters. The IDT version is specifically identified by the ATQG suffix indicating the package and temperature grade.
