Each of the 28 I/Os is configured as push-pull output or input, and the part generates an interrupt output on pin change — useful for a keypad matrix or sensor bank where the host MCU doesn't want to poll. Each output can source 4.5 mA or sink 10 mA, enough to drive a standard LED directly or switch a small-signal relay through a transistor. For higher loads, the push-pull stage can be paralleled across multiple pins with firmware coordination. ## Package and rework reality Housed in a 40-TQFN with an exposed pad (6x6 mm body). The pad is the thermal and electrical ground — it needs a good solder joint to the board's ground plane.","metaTitle":"MAX7300ATL+T I²C I/O Expander, 28 I/O, 400 kHz, 40-TQFN","metaDescription":"MAX7300ATL+T I²C I/O expander from Analog Devices. 28 push-pull I/Os, 400 kHz clock, 2.5-5.5V supply, -40 to +125°C.
