PCF8574RGTR

TEXAS INSTRUMENTS  PCF8574RGTR  输入/输出扩展, 8bit, 100 kHz, I2C, 2.5 V, 6 V, QFN

The is a remote 8-bit I/O Expander for I²C-bus designed for VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I²C 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.
