CMOS IC
LC75850E, 75850W
1/3 Duty General Purpose LCD Drivers
Overview
The LC75850E and LC75850W are general purpose LCD drivers for use in microprocessor controlled applications such as radio tuner frequency displays.
Functions
• Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD driver techniques for a maximum of 156 segments.
• Power saving mode allows the backup function to be switched on or off and all segments to be turned off unconditionally.
• Can be controlled by three serial data lines (CE, CL, and DI) from the microprocessor. (CCB handling)
• High generality, since segment data can be displayed without going through a decoder.
• The INH pin unconditionally turns off display. • The LCD drive bias voltage can be provided internally or
externally.
