NJU640VB
MATRIX 40-QUT SEGMENT DRIVER
NJU6407B serial input, 40-out segment driver matrix LCDs, especial useful extension driver controller drivers like NJU6408B.
consists 40-bit (two 20-bit) shift register, 40-bit latch, high voltage drivers.
shift direction each 20-bit shift register independently each other, consequently efficient extension driver allocation according number characters easy wiring with panel performed.
40-driver have level voltage inputs drive LCD, adjustable driving voltage according panel supplied from external power source.
