PCF8574ADWR Description

Short technical summary and product information.

The PCF8574ADWR from Philips is a versatile 8-bit input/output (I/O) expander that communicates via the two-line bidirectional I2C bus. This device is designed for 2.5V to 6V VCC operation, making it compatible with a wide range of microcontrollers.

 

Key features include a low standby current consumption of only 10 μA maximum, and latched outputs with high-current drive capability suitable for directly driving LEDs. Each of the 8 quasi-bidirectional I/O ports can function as either an input or an output without requiring a separate data-direction control signal. At power-on, the I/Os are high.

 

The PCF8574ADWR is available in a SOIC package, suitable for surface mount applications. Its latch-up performance exceeds 100 mA per JESD 78, Class II, ensuring robust operation in demanding environments.
