Note 3. Unless otherwise specified, Min/Max limits apply across TA = 0° to +70°C. All typical values
are or TA = +25°C and VCC = 5V.
Note 4. All currents into device pins ahown as positive, out of device pins as negative, all voltages
referenced to GND unless otherwise sepcified. All values shown as Max or Min on absolute
value basis.
Note 5. For saturation mode the segment output currents are externally limited and ratioed.
