10 DC CHARACTERISTICS
VDD = 2 to 6 V; VSS =0V; VLCD =VDD 2VtoVDD 6V;Tamb = 40 to +85 °C; unless otherwise specied.
Notes
1. VLCD ≤ VDD 3 V for 13bias.
2. LCD outputs are open-circuit; inputs at VSS or VDD; external clock with 50% duty factor; I2C-bus inactive.
3. Resets all logic when VDD < VPOR.
4. Periodically sampled, not 100% tested.
5. Outputs measured one at a time.
