It operates from a 4.75V to 5.25V supply and sinks 48 mA per output on the low side, or 64 mA depending on the direction — the open-drain structure means the high-level output is pulled up externally, so the actual drive current is set by the pull-up resistor and the bus capacitance. The single-element, 8-bit layout maps cleanly onto an 8-bit data bus or a byte-wide control signal set. ## 20-SOIC package and rework considerations Where is pin 1? The SOIC-20 uses a molded notch and a dot on the top surface — standard orientation. The supplier device package is 20-SOIC, matching the JEDEC MO-119 variation for the wide body.","metaTitle":"Renesas 74FCT621TSOG Transceiver, Open Drain, 20-SOIC","metaDescription":"Active Renesas 74FCT621TSOG 8-bit non-inverting transceiver with open-drain outputs. 4.75-5.25V supply, -40 to +85°C, 20-SOIC.
