This datasheet also covers the PCF8574 variant, as both devices belong to the same remote 8-bit i/o expander family and are provided as variant models within a single manufacturer datasheet.
General Description
This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation.
The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)].
Key Features
1 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
2.
