PCF8574ADW +BOM

8-bit 2.5- to 5.5-V I2C/SMBus I/O expander with interrupt

PCF8574ADW General Description

One of the standout features of the PCF8574ADW is its high-current drive capability, making it ideal for driving LEDs directly from the I/O ports. This eliminates the need for additional circuitry, simplifying the design process for lighting applications

PCF8574ADW

Key Features

  • Low standby-current consumption of 10 µA max
  • I2C to parallel-port expander
  • Open-drain interrupt output
  • Compatible with most microcontrollers
  • Latched outputs with high-current drive capability for directly driving LEDs
  • Latch-up performance exceeds 100 mA Per JESD 78, Class II
