MAX7315
Functional Overview
The MAX7315 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 MAX7315’s
supply voltage. The MAX7315 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 MAX7315. The ports default to inputs on power-up.
Port Inputs and Transition Detection
An input ports register reflects the incoming logic levels
of the port pins, regardless of whether the pin is
defined as an input or an output. Reading the input
