HLF8574 Description
TheHLF8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C). The device consists of an 8-bit quasi-bidirectional port and an I2C-bus interface.
HLF8574 Key Features
- Operating supply voltage 2.5 to 6 V
- Low standby current consumption of 10 µA maximum
- I2C to parallel port expander
- Open-drain interrupt output
- 8-bit remote I/O port for the I2C-bus
- patible with most microcontrollers
- DIP16, or space-saving SO16 or SSOP20 packages
