V1 and V3 should be near the V
level, and V4 and V2 should be near the V
level. All these
voltage pairs should be separated by less than
V, which is the range within which RON, the
LCD drive circuits’ output impedance, is stable. Note that
V depends on power supply voltage

2. Input and output currents are excluded. When a CMOS input is floating, excess current flows
from the power supply through to the input circuit. To avoid this, VIH and VIL must be held to
V
CC
and GND levels, respectively.
3. Applies to serial-latch operation.
4. Applies to shift register operation.
