Интерфейсные элементы - Расширительные модули ввода-вывода MAX7319ATE+

Расширитель I/O , 40 кГц, I2C, 1.71 В, 5.5 В, TQFN

The MAX7319ATE+ is an I2C port expander with eight inputs and maskable transition detection in 16 pin TQFN package. The MAX7319 2-wire serial-interfaced peripheral features eight input ports with selectable internal pull-ups, overvoltage protection to +6V and transition detection with interrupt output. All input ports are continuously monitored for state changes. Transitions are latched, allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert the INT output. When the MAX7319 is subsequently accessed through serial interface any pending interrupt is cleared.
