74FCT543PBCTSO

Buffers, Drivers, Receivers, Transceivers Overview

The IDT 74FCT543PBCTSO is a fast CMOS octal latched transceiver in the FCT series. It features one function with eight bits per element and true output polarity. The device operates within a supply voltage range of 4.75V to 5.25V and supports TTL input and output levels. It provides three-state outputs with a low-level output current of 64mA and a high-level output current of -32mA. The propagation delay is typically 8.5ns. It functions as a registered bus transceiver with independent control, housed in a 24-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PBCTSO' against official IDT documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-SOIC form factor. Confirm RoHS compliance status through the manufacturer's latest certification documents before integration into regulated assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting, latched transceiver is required for 5V logic applications. The FCT series offers faster switching speeds compared to standard 74LS equivalents. Consider the 24-pin SOIC package constraints and thermal dissipation requirements for surface-mount assembly processes.
