.. 19-3056; Rev 0; 10/03 8-Port I/O Expander with LED Intensity Control and Interrupt General Description The MAX7315 I2C™-/SMBus-patible serial interfaced peripheral provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection. A ninth port can be used for transition detection interrupt or as a generalpurpose output. The outputs are capable of directly driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V. PWM current drive is integrated with 8 bits of control. Four bits are global control and apply to...
