LC74711

The LC74711 is designed as one kind of CMOS LSI for applications involving microcomputer control of on-screen character and graphics displays. Built-in character ROM supplies 128 alphanumerics and each character is generated in a 12 by 18 pixel format. The display is capable of supporting a maximum of 288 characters within a 24 characters by 12 line array.

Features of the LC74711 are:(1)screen construction 24 characters x 12 lines;(2)number of characters displayed maximum 288 characters capacity;(3)display control ROM (line ROM) 64 lines (line unit control: 24 character construction);(4)display RAM: 176 characters (supporting extend character selection);(5)character construction: 12 x 18 pixels;(6)character set: 128 types of characters;(7)character size: 4 horizontal types and 4 vertical typs.

The absolute maximum ratings of the LC74711 can be summarized as:(1)Maximum supply voltage: VSS-0.3 to VSS+7.0 V;(2)Maximum input voltage:VSS-0.3 to VDD+0.3 V;(3)Maximum output voltage: VSS-0.3 to VDD+0.3 V;(4)Allowable power dissipation: 300 mW;(5)Operating temperature:30 to + 70 °C;(6)Storage temperature:40 to + 125 °C.
