Notes: 1. This is a resistance value between the X and V pins (either of VH, VL, or VM) when a load
current is applied to one of x1 to x240 pins. These values are regulated under the conditions of
VLCD = VH = 21.75 V, VEE = VL = –18.5 V, VM = 1.75 V, GND = 0 V, Use VH, VL, and VM in
the range of VLCD – VM≥VH – VM = 21.5 to 7.5 V, VEE – VM≤VL – VM = –21.5 to –7.5 V, with
the relation of VH > VM > VL.
2. The current applied between the input and output is excluded. When an input to a CMOS gate is
at an intermediate level, through current flows between the power supplies, and the power
supply current increases. Therefore, use V_IH = V_CC and V_IL = GND.
3. The voltage relationship of each signal is as follows :
