Интерфейсные элементы - Расширительные модули ввода-вывода 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.
