[1] V_LCD > 3 V for ¹â„₃ bias.
[2] LCD outputs are open-circuit; inputs at V_SS or V_DD; external clock with 50 % duty factor; I²C-bus inactive.
[3] For typical values, see Figure 20.
[4] For typical values, see Figure 21.
[5] The I²C-bus interface of PCA85162 is 5 V tolerant.
[6] When tested, I²C pins SCL and SDA have no diode to V_DD and may be driven to the V_I limiting values given in Table 17 (see Figure 19
as well).
[7] Propagation delay of driver between clock (CLK) and LCD driving signals.
[8] Periodically sampled, not 100 % tested.
[9] Outputs measured one at a time.
