[1] VLCD > 3 V for 1⁄3 bias.
[2] LCD outputs are open-circuit; inputs at VSS or VDD; external clock with 50 % duty factor; I2C-bus inactive.
[3] The I2C-bus interface of PCF8562 is 5 V tolerant.
[4] When tested, I2C pins SCL and SDA have no diode to VDD and may be driven to the VI limiting values given in Table 16 (see Figure 19
as well).
[5] Propagation delay of driver between clock (CLK) and LCD driving signals.
[6] Periodically sampled, not 100 % tested.
[7] Outputs measured one at a time.
