MAX7323ATE+ Description

Short technical summary and product information.

The MAX7323ATE+ is an I2C serial-interfaced peripheral from Analog Devices, offering eight I/O ports for expanding system capabilities. Four of these ports are configured as push-pull outputs, while the other four are open-drain I/O ports that are overvoltage protected up to +6V.

 

This device supports a 400kHz I2C serial interface and operates within a voltage range of +1.71V to +5.5V. The push-pull and open-drain outputs are rated to sink 20mA, making them suitable for driving LEDs. The four I/O ports configured as inputs are continuously monitored for state changes, with an open-drain INT output indicating transitions. The interrupt is latched, allowing detection of transient changes.

 

The MAX7323ATE+ utilizes two address inputs with four-level logic to allow for 16 I2C slave addresses. It is available in a 16-pin TQFN package and is specified for the automotive temperature range of -40°C to +125°C. Applications include cell phones, SAN/NAS, servers, notebooks, and RAID systems.
