MAX6958 Description
The MAX6958/MAX6959 pact multiplexed mon-cathode display drivers interface microprocessors to seven-segment numeric LED digits, or discrete LEDs through an SMBus™- and I2C-patible 2-wire serial interface. The 2-wire serial interface uses fixed 0.8V/2.1V logic thresholds for patibility with 2.5V and 3.3V systems when the display driver is powered from a 5V supply. The MAX6958/MAX6959 drive up to four 7-segment...
