MAX7323ATE+, Расширитель I/O, 400 кГц, I2C, 1.71 В, 5.5 В, TQFN

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.
