Typical applications include bidirectional data buses in industrial controllers, telecom line cards, and memory-interface buffers where 5V logic levels are still in use. ## Output drive and bus loading The transceiver can source 32 mA and sink 64 mA per output. The 3-state outputs let multiple transceivers share the same bus lines. ## Package and assembly notes The 24-SOIC (0.295\", 7.50 mm width) is a standard JEDEC footprint shared with many 24-pin SOIC parts. ## Lifecycle and compliance For long-term supply assurance, the 74FCT family has been stable for years and is widely second-sourced across the industry.","metaTitle":"CY74FCT543ATSOC 74FCT Transceiver, Non-Inverting, 24-SOIC","metaDescription":"CY74FCT543ATSOC is an 8-bit non-inverting transceiver with 3-state outputs, 4.75V–5.25V supply, -40°C to 85°C range.
