It handles the multiplexing, segment current limiting, and BCD decoding internally, so the host MCU only needs to send digit data over a 4-wire serial link. Typical applications include panel meters, industrial readouts, point-of-sale displays, and any numeric or alphanumeric LED indication where a through-hole DIP package suits the assembly process. ## Temperature grade and environment Rated for 0°C to 70°C commercial temperature range. That covers most indoor equipment — bench instruments, control panels, point-of-sale terminals — but not outdoor or unheated enclosures. If the display lives in a conditioned space, this grade is fine. ## Lifecycle and sourcing The MAX7219CNG+ carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"MAX7219CNG+ LED Display Driver, 8-Digit 7-Segment","metaDescription":"MAX7219CNG+ from Analog Devices: LED display driver IC, 8 digits, 7-segment + DP, 4V to 5.5V supply, 4-wire serial interface, 24-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Interface":"4-Wire Serial","Display Type":"LED","Configuration":"7 Segment + DP","Mounting Type":"Through Hole","Package / Case":"24-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Supply":"330 mA","Voltage - Supply":"4V ~ 5.5V","Digits or Characters":"8 Digits","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"24-PDIP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.60000","currency":"USD"},{"qty":10,"price":"$10.66300","currency":"USD"},{"qty":25,"price":"$10.22080","currency":"USD"},{"qty":100,"price":"$9.00530","currency":"USD"},{"qty":250,"price":"$8.56328","currency":"USD"},{"qty":500,"price":"$8.01082","currency":"USD"},{"qty":1000,"price":"$7.34785","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX7219-MAX7221.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MAX7219CNG+ and MAX7219CWG+?","answer":"The MAX7219CNG+ comes in a 24-DIP through-hole package, while the MAX7219CWG+ is the same driver in a 24-SOIC surface-mount package. The die and electrical specs are identical; the choice is purely board-assembly method."},{"question":"How to cascade multiple MAX7219CNG+?","answer":"Cascading is done by connecting the DOUT pin of the first device to the DIN pin of the next, sharing the same CLK and LOAD lines. The host sends a 16-bit data packet for each driver in sequence, most-significant-digit first. Up to 8 drivers can be daisy-chained without additional I/O pins."},{"question":"What is the maximum current per segment on MAX7219?","answer":"The maximum segment current is set by an external resistor (RSET) between the ISET pin and GND. The datasheet provides a resistor-value table; typical values range from 10 mA to 40 mA per segment depending on display brightness and supply voltage."},{"question":"Where can I buy MAX7219CNG+?","answer":"We source this part to order.
