Five-digit 7-segment LED driver with 3-wire serial control
The Analog Devices MAX6950CEE+ drives 5 digits of 7-segment LED displays via a 3-wire serial interface. Supply range spans 2.7 V to 5.5 V.
What the ratings mean for your BOM
The 10 mA supply current (typical) covers the driver's own logic and oscillator, not the LED segment current — external resistors set per-segment peak current. At 5 V the 3-wire serial logic levels are 5 V tolerant, so it mates directly with 5 V microcontrollers without level shifting. The 0°C to 70°C operating range limits this part to commercial indoor equipment: office appliances, point-of-sale displays, test equipment front panels.
Lifecycle and sourcing reality
The MAX6950CEE+ carries an Active product status with ROHS3 compliance. The date-code and marking on incoming stock should be verified against the manufacturer's known laser-etch font for this package — a clean trace back to the authorized channel is the standard screen for this part.
