The PCF8574 and PCF8574A have addresses ranging from 0x38 to 0x3F (up to eight PCF8574A devices may be used on the same I2C bus).
• A total of 16 PCF8574 and PCF8574A devices may be used on the same I2C bus.
The PCF8574 and PCF8574A use the serial clock (SCL) and serial data (SDA) I2C lines to communicate with the bus controller.
