Ordering number:ENN4467 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.
