Notes: 1. Indicates the resistance between one pin from Y1–Y240 and another pin from V1–V4, when load
current is applied to the Y pin; defined under the following conditions.
VLCD–GND = 40V
V1, V3 = VLCD – {1/20(VLCD–GND)}
V2, V4 = GND + {1/20(VLCD–GND)}
V1 and V3 should be near VLCD level, and V2 and V4 should be near GND level (Figure 6). All
voltage must be within
V.
V is the range within which R
, the LCD drive circuits’ output
impedance, is stable. Note that
V depends on power supply voltage VLCD–GND (Figure 7).
2. Input and output current is excluded. When a CMOS input is floating, excess current flows from
the power supply through the input circuit. To avoid this, VIH and VIL must be held to V
CC
and
GND levels, respectively.
3. Applies to standby mode.
