Each of the nine I/O lines is open-drain, rated for 12 mA source/sink per pin — enough to drive small LEDs, relay coils, or pull signal lines without an external buffer. On-chip EEPROM stores the I/O configuration and POR state, so the expander powers up with the correct pin directions and output levels — no host re-initialization needed after a brown-out or cold start. ## Active production, RoHS3 compliant Available in Tape & Reel (TR) or Cut Tape (CT) — the TR suffix on the order code signals reel packaging for automated pick-and-place.","metaTitle":"DS4520E+TRL I²C I/O Expander, 9-Ch, 400 kHz, 16-TSSOP","metaDescription":"Analog Devices DS4520E+TRL I²C I/O expander, 9 open-drain I/O, 400 kHz, 2.7-5.5 V, -40 to +85°C, 16-TSSOP.
