LC75850E

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. Power supply voltage: 4.5 to 8V.
