MAX7316
Functional Overview
The MAX7316 is a general-purpose input/output (GPIO)
peripheral that provides eight I/O ports, P0–P7, con-
trolled through an I2C-compatible serial interface. A 9th
output-only port, INT/O8, can be configured as an inter-
rupt output or as a general-purpose output port. All out-
put ports sink loads up to 50mA connected to external
supplies up to 5.5V, independent of the MAX7316’s
supply voltage. The MAX7316 is rated for a ground cur-
rent of 190mA, allowing all nine outputs to sink 20mA at
the same time. Figure 1 shows the output structure of
the MAX7316. The ports default to inputs on power-up.

AD0
Address Input. Sets device slave address. Connect to either GND, V+, SCL,
or SDA to give four logic combinations. See Table 1.
