Driving LEDs with Open Drain Port Expander Outputs


要約: This application note discusses techniques for driving LEDs with the MAX6964, MAX6965, MAX7313, MAX7314, MAX7315 and MAX7316 I/O expanders (GPIOs). These techniques can be applied to other I/O expanders with open-drain outputs, as well as other ICs with open-drain logic outputs. (Types like the 74HC06 and 74HC07 can be used for high current drive applications).
