Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor when sourcing this specific part number. Confirm the package type matches the required SOIC-20 or similar surface-mount form factor if applicable to the design. Ensure the operating temperature range meets the -40°C to +85°C industrial specification. Cross-reference the FCT series compatibility with existing system logic levels. Validate that the three-state output functionality aligns with the intended bus architecture requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal buffering with high-speed performance characteristics typical of the FCT series. Consider the 9 ns propagation delay for timing-sensitive applications. The industrial temperature rating makes it suitable for environments with wider thermal variations compared to commercial grade parts. Ensure the 5V supply voltage constraint fits the system power budget. The three-state feature allows for easy integration into shared data buses without additional gating logic.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader FCT logic family, which offers BiCMOS performance with CMOS compatibility. It serves as a standard solution for interfacing between different logic families or driving heavy capacitive loads on system buses. The octal format consolidates multiple buffer functions into a single package, reducing board space and simplifying routing compared to using individual single-buffer ICs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include CD74FCT541M from Texas Instruments and CY74FCT541ATSOC from Texas Instruments. These alternatives share the same logical function and pinout but may differ in packaging or specific electrical parameters such as propagation delay or drive strength. Verify mechanical dimensions and thermal characteristics before substitution.
