A high output is intended to light the segment. Common cathode , meaning the negative connection of all of the LEDs is tied together. The outputs are open-collector but have internal 2K ohm pull-up resistors and have a maximum low-level output sink current of 6 milliamperes 6mA. All segments are extinguished when a low logical zero signal is applied to pin 4 OUT. A PWM pulse-width modulated signal can be applied to this pin to provided varying brightnesses to the LED display being driven, allowing user control of LED dimming for applications such as power saving by decreasing the brightness during times of low ambient light.
