Ordering number : EN5597 CMOS LSI LC75834E, 75834W, 75834JE 1/4 Duty General-Purpose LCD Drivers Overview The LC75834E, LC75834W, and LC75834JE are 1/4-duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75834E and LC75834W can drive an LCD with up to 136 segments directly, the LC75834JE can drive an LCD with up to 120 segments directly. The LC75834E and LC75834W and LC75834JE can also control up to 8 general-purpose output ports. Since the LC75834E, LC75834W, and LC75834JE use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.
