The following is a description of the range of power supply voltage for liquid crystal display drive.
Apply positive voltage to VRH1 = VRH2 and negative voltage to VRL1 = VRL2 within the
V
range. This range allows stable impedance on driver output (RON). Notice that
V depends on
power supply voltage VLCD–VEE.

5. Input and Output currents are excluded. When a CMOS input is floating, excess current flows
from the power supply to the input circuit. To avoid this, ViH and ViL must be held to V
CC
and
GND levels, respectively.
6. Specified at +75
°
C for die products.
