DESCRIPTION
The SED1640 is the 80-segment (column) output driver that is appropriate to driving of a large-capacity, dot-matrix
LCD panel.
The chip has been designed to improve the LCD display quality and it provides the high-speed enable chain
method useful for lower power operation. The flat chip design allows more compact LCD panel production. The
logic power supply allows low-voltage operation in a wide range of applications.
