19-3170; Rev 4; 4/05 18-Port GPIO with LED Intensity Control, Interrupt, and Hot-Insertion Protection General Description The MAX7314 I2C™-compatible serial interfaced peripheral provides microprocessors with 16 I/O ports plus one output-only port and one input-only port. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA and 5.5V, or a logic input with transition detection. The output-only port can be assigned as an interrupt output for transition detection. The outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V. Eight-bit PWM current control is built in for all 17 output ports.
