MAX7300ATL+

The MAX7300ATL+ is a 28 port I/O expander in 40 pin TQFN package. This compact, 2-wire serial interfaced, I/O expansion peripheral provides microprocessors with 28 ports. Each port is individually user configurable to either a logic input or logic output. The device ports can be configured as either a push-pull logic output capable of sinking 10mA and sourcing 4.5mA or a schmitt logic input with optional internal pull-up. Seven ports feature configurable transition detection logic which generates an interrupt upon change of port logic level. The MAX7300 is controlled through an I2C compatible 2-wire serial interface and uses four level logic that allow 16 I2C addresses from only two select pins.

• Supply voltage range is 2.5V to 5.5V
• Maximum shutdown current is 11μA
• 400Kbps I2C compatible serial interface
• Serial clock frequency is 400KHz
