MAX6958 2-Wire Interfaced, 3V to 5.5V, 4-Digit, 9-Segment LED Display Drivers with Keyscan

2-Wire Interfaced, 3V to 5.5V, 4-Digit, 9-Segment LED Display Drivers with Keyscan. The MAX6958/MAX6959 compact multiplexed common- cathode display drivers interface microprocessors to seven-segment numeric LED digits, or discrete LEDs through an SMBus™- and I²C-compatible 2-wire serial interface. The 2-wire serial interface uses fixed 0.8V/2.1V logic thresholds for compatibility with 2.5V and 3.3V systems when the display driver is powered from a 5V supply.
