MAX1609 Datasheet (Maxim) - Octal SMBus-to-Parallel I/O Expanders

MAX1609, Octal SMBus-to-Parallel I/O Expanders

The MAX1608/MAX1609 provide remote input/output (I/O) expansion through an SMBus™ 2-wire serial interface.

Each device has eight high-voltage open-drain outputs that double as TTL-level logic inputs, providing continuous bidirectional capabilities.

The open-drain outputs tailor the MAX1608/MAX1609 f

MAX1609 Features

* of both devices include thermaloverload and output-overcurrent protection, ultra-low supply current, and a wide +2.7V to +5.5V supply range. The MAX1608/MAX1609 are available in space-saving 16-pin QSOP packages. o 8 General-Purpose Digital I/O Pins (withstand +28V) o SMBus 2-Wire Serial Interface o
