LC79430D

The LC79430D is designed as one kind of large-scale dot matrix LCD common driver LSI. This device 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 invrease the IC's number of bits. This device also can be used in conjunction with segment driver LC79400D to drive a wide-screen LCD panel.

Features of the LC79430D are:(1)on-chip LCD drive circuit (80 bits);(2)display duty selection ranging from 1/64 to 1/256;(3)on-chip input / output pins support further increases in bit number;(4)supports externally supplied bias voltage;(5)on-chip 80-bit bidirectional shift register (supports 40-bit x 2 divison);(6)supports single mode (80-bit shift register) and dual mode (40-bit x 2 shift register) applications.

The absolute maximum ratings of the LC79430D can be summarized as:(1)maximum supply voltage (logic): -0.3 to +7.0 V;(2)maximum supply voltage (LCD): 0 to 35 V;(3)maximum input voltage: -0.3 to VDD+0.3 V;(4)storage temperature range: -40 to +125 .
