LC79430KNE集成電路（IC）的顯示驅(qū)動器規(guī)格書PDF中文資料

Overview

The LC79430KNE is a large-scale dot matrix LCD common driver LSI. The LC79430KNE contains an 80-bit bidirectional shift register and is equipped with a 4-level LCD driver. The input/output pins for cascade connection can be used to further increase the IC’s number of bits. The LC79430KNE can be used in conjunction with segment driver LC79401KNE (QIP100E) to drive a wide-screen LCD panel.
