Overview
The LC4104 is a segment driver LSI for large-scale dot matrix LCD displays. The LC4104 latches 160-bits of display data transferred from the controller over a 4- or 8-bit parallel interface and generates the LCD drive signals. In conjunction with the LC4102 common driver, the LC4104 forms a chip set that can drive large-screen LCD panels.

Features
• High-voltage CMOS (P-sub) process
• LCD drive voltage: 36 V
• Logic system power-supply voltage: 2.7 to 5.5 V
• Maximum fcp: 12 MHz (VDD = 5 V ±10%),  10 MHz (VDD = 2.7 to 4.5 V)
• Slim chip (The output pads are located along one of the long sides.)
• Parallel input circuit can be switched between 4 and 8 bits.
• Output directionality switching
• DISPOFF function (Holds the LCD drive voltage at a fixed level.)
• Display duty ratios: 1/160 to 1/480
• Appropriate for COG (chip on glass) mounting. (A gold bump structure is adopted in the pad areas.)
