MAX7313
Functional Overview
The MAX7313 is a general-purpose input/output (GPIO)
peripheral that provides 16 I/O ports, P0–P15, con-
trolled through an I2C-compatible serial interface. A
17th output-only port, INT/O16, can be configured as
an interrupt output or as a general-purpose output port.
All output ports sink loads up to 50mA connected to
external supplies up to 5.5V, independent of the
MAX7313’s supply voltage. The MAX7313 is rated for a
ground current of 350mA, allowing all 17 outputs to sink
20mA at the same time. Figure 1 shows the output
structure of the MAX7313. The ports default to inputs on
power-up.
Port Inputs and Transition Detection
Input ports registers reflect the incoming logic levels of
the port pins, regardless of whether the pin is defined
