ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(V+ = 5V ±10%, R SET = 9.53k Ω±1%, T A = T MIN to T MAX , unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Voltage (with respect to GND)
V+............................................................................-0.3V to 6V DIN, CLK, LOAD, CS ...............................................-0.3V to 6V All Other Pins.............................................-0.3V to (V+ + 0.3V)Current
DIG 0–DIG 7 Sink Current..............................................500mA SEG A–G, DP Source Current........................................100mA Continuous Power Dissipation (T A = +85°C)Narrow Plastic DIP (derate 13.3mW/°C
above +70°C)..............................................................1066mW Wide SO (derate 11.8mW/°C above +70°C).................941mW Narrow CERDIP (derate 12.5mW/°C above +70°C)...1000mW
Operating Temperature Ranges (T MIN to T MAX )
MAX7219C_G/MAX7221C_G ..............................0°C to +70°C MAX7219E_G/MAX7221E_G............................-40°C to +85°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10s).................................+300°C
