Интерфейсные элементы - Расширительные модули ввода-вывода PCF8575CTS/1,112

Расширитель I/O , 16бит, 400 кГц, I2C, 4.5 В, 5.5 В, SSOP

The PCF8575CTS/1,112 is a 16-bit remote I/O Expander for I²C-bus. It provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I²C-bus). The device consists of a 16-bit quasi-bidirectional port and an I²C-bus interface. The PCF8575C has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. It also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I²C-bus.

• Low standby current consumption of 10µA maximum
• 400KHz fast I²C bus
• Open-drain interrupt output
• Compatible with most microcontrollers
• Latched outputs with high current drive capability for directly driving LEDs
• Address by 3 hardware address pins for use of up to 8 devices
