2-Wire-Interfaced, 16-Bit, I/O Port Expander
with Interrupt and Hot-Insertion Protection
General Description
The MAX7318 2-wire-interfaced expander provides 16-
bit parallel input/output (I/O) port expansion for SMBus™
and I
2
C applications. The MAX7318 consists of input
port registers, output port registers, polarity inversion
registers, configuration registers, and an I
2
C-compatible
serial interface logic compatible with SMBus. The sys-
tem master can invert the MAX7318 input data by writing
to the active-high polarity inversion 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 MAX7318 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 MAX7318 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 an SMBus timeout function,
refer to the MAX7311 data sheet.
