PCF8574RGTR

Расширитель I/O, 8бит, 100 кГц, I2C, 2.5 В, 6 В, QFN.

The PCF8574RGTR is a remote 8-bit I/O Expander for I?C-bus designed for VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I?C interface (serial clock (SCL), serial data (SDA)). The device features an 8-bit quasi-bidirectional I/O port (P0-P7), including latched outputs with high-current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. At power on, the I/Os are high. In this mode, only a current source to VCC is active.
