General Description
The MAX7312 2-wire-interfaced expander provides 16-bit
parallel input/output (I/O) port expansion in SMBus and
I2C applications. The MAX7312 consists of input port
registers, output port registers, polarity inversion regis-
ters, configuration registers, a bus timeout register, and
an I2C-compatible serial interface logic, compatible with
SMBus. The system master can invert the MAX7312 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
an output. A power-on reset (POR) initializes the 16 I/Os
as inputs. Three address select pins configure the part
to one of 64 slave ID addresses.
The MAX7312 supports hot insertion. All port pins, the
INT output, SDA, SCL, and the slave address inputs
AD0-2 remain high impedance in power-down (Vt = 0V)
up to 6V.
The MAX7312 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 with integrated 100k
Ω
pullup resistors, refer to the MAX7311 data sheet.
