The LC75873NE and LC75873NW are 1/3‑duty general‑purpose LCD display drivers that can directly drive up to 204 segments and provide four general‑purpose output ports. They support both 1/2‑bias and 1/3‑bias drive techniques and use a serial CCB bus format for communication with a system controller.
The document includes pin assignments, functional descriptions, electrical characteristics, recommended external components, and sample application circuits for both 1/2‑bias and 1/3‑bias LCD panels.
