The MAX7311 2-wire-interfaced expander provides 16-bit
parallel input/output (I/O) port expansion for SMBus™
and I
port registers, output port registers, polarity inversion reg-
isters, configuration registers, a bus timeout register, and
an I
SMBus. The system master can invert the MAX7311 input
data by writing to the active-high polarity inversion regis-
ter. The system master can enable or disable bus timeout
by writing to the bus timeout register.
Any of the 16 I/O ports can be configured as an input or
output. A power-on reset (POR) initializes the 16 I/Os
as inputs. Three address select pins configure one of
64 slave ID addresses.
The MAX7311 supports hot insertion. All port pins, the
INT output, SDA, SCL and the slave address inputs
AD0–2 remain high impedance in power down (V+ =
0V) with up to 6V asserted upon them.
The MAX7311 is available in 24-pin SO, SSOP, TSSOP,
and thin QFN packages and is specified over the -40°C
to +125°C automotive temperature range.
For applications requiring I/Os without pullup resistors,
refer to the MAX7312 data sheet.
