Maxim Integrated (MAX7219CNG+) LED Driver, 4V to 5.5V input, 8 Outputs

Product OverviewThe MAX7219CNG+ is a 8-digit serially interfaced LED Display Driver for LEDmatrix displays. The MAX7219 is compact, serial input/output common-cathodedisplay drivers that interface microprocessors (µPs) to 7-segment numeric LEDdisplays of up to 8 digits, bar-graph displays or 64 individual LEDs. Includedon-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digitdrivers and an 8x8 static RAM that stores each digit. Only one external resistoris required to set the segment current for all LEDs. A convenient 4-wire serialinterface connects to all common µPs. Individual digits may be addressed andupdated without rewriting the entire display. The MAX7219 also allow the user toselect code-B decoding or no-decode for each digit. The devices include a 150µAlow-power shutdown mode, analogue and digital brightness control, a scan-limitregister that allows the user to display from 1 to 8 digits and a test mode thatforces all LEDs on.Individual LED segment controlDecode/no-decode digit selection150µA Low-power shutdown (data retained)Digital and analogue brightness controlDisplay blanked on power-upDrive common-cathode LED displayApplicationsIndustrial, Automation & Process Control, Metering, Consumer ElectronicsProduct InformationNo. of Digits: 8No. of Segments: 7Driver Case Style: DIPNo. of Pins: 24PinsSupply Voltage Min: 4VSupply Voltage Max: 5.5VInterface Type: SerialOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: MAX7219; MAX7221MSL: MSL 1 - Unlimited
