PCF8574 Module IO Expansion Board for I2C Bus is designed for 2.5V to 6V VCC operation.

The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface 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.
