HLF8574 Datasheet (HLF) - Remote 8-bit I/O expander

HLF8574, Remote 8-bit I/O expander

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.

The HLF8574 has a low current consumption and includes
