UMW R PCF8574 8-Bit I/O Expander for I 2C Bus Description The PCF8574 is mainly used to Features expand general-purpose input and output (GPIO) ports. Port ●• I/O interface expander controlled by I2C data is transmitted via the standard two-line I2C ●• Power supply voltage: 1.4V ~ 5.5 V ●• Operating temperature: - 40 °C ~ +85 °C GPIO ports (P0~P7), which can directly drive LEDs. ●• Standby power consumption: <1uA Each quasi-bidirectional GPIO port can be used as an ●• Can drive LED directly ●• Open-drain interrupt output protocol. The PCF8574 features 8-bit quasi-bidirectional input or output without the use of a data-direction control signal. After power on, all GPIO ports are high. Applications ●• Communication cabinet ●• Servers ●• Industrial automation ●• Products with GPIO-Limited Processors www.umw-ic.com 1 UTD Semiconductor Co.,Limited  PDF
