LC75874E, 75874W
1/4-Duty General-Purpose LCD Display Driver
Overview
The LC75874E and LC75874W are 1/4-duty generalpurpose microprocessor-controlled LCD driver that can be used in applications such as frequency display in products with electronic tuning.
In addition to being able to drive up to 264 segments directly, the LC75874E and LC75874W can also control up to 8 general-purpose output ports.
Since the LC75874E and LC75874W 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 V, regardless of the logic block power-supply
voltage.
