Surface-mount assembly with tube delivery — the tube quantity is the standard 24-QSOP tube count; no reel or tape option is listed for this ordering code, so hand-place or low-volume lines are the natural fit.","metaTitle":"74FCT543ATQG Renesas 74FCT Transceiver, 8-bit, 24-QSOP","metaDescription":"74FCT543ATQG Renesas 74FCT octal transceiver, 5V supply, 15mA/64mA drive, -40°C to 85°C, 24-QSOP.
