General Description
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 for use in load-switching and other
level-shifting applications as well as general-purpose I/O
applications.
Two complete sets of registers allow the device and its
outputs to be toggled between two states using the
SMBSUS
input, without the inherent latency of reprogram-
ming outputs over the serial bus. The eight I/O lines are
continuously monitored and can be used as inputs. Each
line can generate asynchronous maskable interrupts on
the falling edge, the rising edge, or both edges.
For load-switching applications, the MAX1608 is designed
to drive N-channel MOSFETs, and its outputs are low
upon power-up; the MAX1609 is designed to drive P-
channel MOSFETs, and its I/Os are high impedance upon
power-up. Other features of both devices include thermal-
overload and output-overcurrent protection, ultra-low sup-
ply current, and a wide +2.7V to +5.5V supply range. The
MAX1608/MAX1609 are available in space-saving 16-pin
QSOP packages.
