Product Overview
The PCF8574TD is an 8-bit remote I/O Expander for I²C-bus. It provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I²C-bus). The device consists of an 8-bit quasi-bidirectional port and an I²C-bus interface. The PCF8574 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. It also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I²C-bus.
- Open-drain interrupt output
- Compatible with most microcontrollers
- Latched outputs with high current drive capability for directly driving LEDs
- Low standby current consumption of 10µA maximum
