Maxim Integrated (MAX7323ATE+) I/O Expander, 400 kHz

Product Overview The MAX7323ATE+ from Maxim Integrated Products is an I2C port expander with 4 push-pull outputs and 4 open-drain I/Os in 16 pin TQFN package. This 2-wire serial interfaced peripheral features eight I/O ports. Four ports are push-pull outputs and the other four are open-drain I/O ports that are overvoltage protected up to +6V independent of the supply voltage. State changes are indicated by the open-drain active-low INT output. The interrupt is latched, allowing detection of transient changes. When the MAX7323 is subsequently accessed through the serial interface, any pending interrupt is cleared. 400KHz I2C serial interface, +1.71V to +5.5V operating voltage Active-low RST input clears serial interface, terminating any I2C communication to or from MAX7323 4 push-pull O/P ports rated at 20mA sink current, 4 open-drain I/O ports rated to 20mA sink current 4 I/O ports are overvoltage protected to +6V Transient changes are latched, allowing detection between read operations Active-low INT output alerts change on inputs Low standby current of 0.6µA Power-on reset voltage of 1.6V, operating temperature range form -40°C to +125°C 4 I/O ports configured as inputs are continuously monitored for state changes (transition detection) Product Information Chip Configuration: - Bus Frequency: 400kHz IC Interface Type: I2C Supply Voltage Min: 1.71V Supply Voltage Max: 5.5V Interface Case Style: TQFN No. of Pins: 16Pins No. of I/O's: 4I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
