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. The MAX7323 uses two address inputs with four-level logic to allow 16 I2C slave addresses. The slave address also determines the power-up logic state for the I/O ports and enables or disables internal 40Kohm pull-ups for the input ports in groups of two ports. It is used in cell phones, SAN/NAS, servers, notebooks and RAID.

• 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
• AD0 and AD2 inputs select from 16 slave addresses
• Low 0.6µA (typ) standby current
• 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)
• Cell Phones; Notebooks; RAID; SAN/NAS; Servers
