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