It runs from a 4.75V to 5.25V supply rail, so it is a straight 5V logic part — not a 3.3V-tolerant device. The single-element, 8-bit architecture is a workhorse for buffered data paths in industrial controllers, telecom line cards, and memory-interface glue logic where you need controlled impedance and low propagation delay. ## 15 mA source, 12 mA sink — bus loading budget Output drive is rated at 15 mA high and 12 mA low, which is typical for a 5V FCT transceiver. That drive strength determines how many standard TTL loads you can fan out on a backplane segment. The 3-state outputs let you wire-OR multiple transceivers on the same bus without contention, as long as only one enable is active at a time. ROHS3 compliant, which covers the latest EU exemption updates.","metaTitle":"CY74FCT2245CTSOCT 74FCT Transceiver, 5V 20-SOIC","metaDescription":"CY74FCT2245CTSOCT is a 74FCT 8-bit non-inverting transceiver with 3-state outputs, 4.75V–5.25V supply, -40°C to 85°C.
