Maxim Integrated (MAX7300ATL+) I/O Expander, 400 kHz

Product Overview 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 Applications Communications & Networking, System Monitoring, Industrial, Consumer Electronics Product Information Chip Configuration: - Bus Frequency: 400kHz IC Interface Type: I2C Supply Voltage Min: 2.5V Supply Voltage Max: 5.5V Interface Case Style: TQFN No. of Pins: 40Pins No. of I/O's: 28I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
