Ordering number : ENA2123 LC79430KNE CMOS LSI Dot-Matrix LCD Drivers http://onsemi.com 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. Features * On-chip LCD drive circuit (80 bits) * Display duty selection ranging from 1/64 to 1/256 * On-chip input/output pins support a further increases in bit number * Supports externally supplied bias voltage * On-chip 80-bit bidirectional shift register (supports 40-bit x 2 division) * Supports single mode (80-bit shift register) and dual mode (40-bit x 2 shift register) applications (1) O1 O80 Single mode (2) O80 O1 (3) O1 O40 and O41 O80 Dual mode (4) O80 O41 and O40 O1 All four of the shift direction selection listed above all supported * Operating power supply voltage/operating temperature include VDD (Logic section) : 2.7 to 5.5V/-20 to +85C VDD-VEE (LCD section) : 12 to 32V/-20 to +85C * CMOS process * 100-pin flat plastic package (QIP100E) Semiconductor Components Industries, LLC, 2013 July, 2013 91912HKPC 20080324-S00002 No. A2123-1/7 LC79430KNE Specifications Absolute Maximum Ratings at Ta = 252C, VSS = 0V Parameter Symbol Maximum supply voltage (Logic) VDD max Maximum supply voltage (LCD) VDD-VEE max Maximum input voltage VI max Storage temperature Tstg Conditions Ratings unit -0.3 to +7.0 V 0 to 35 V *1 -0.3 to VDD+0.3 V -40 to +125 C Note *1 The following relations between elements should be maintained: VDDV1>V2>V5>VEE, VDD-V27V, V5-VEE7V Stresses exceeding Maximum Ratings may damage the device.
