Dot Matrix High Duty LCD Driver
SED1672
I
OVERVIEW
The SED1672 is a 68 output low-power resistance common (row) driver which is suitable for driving a very high
capacity dotmatrix LCD panels up to a duty ratio of 1/300. It is intended to be used in conjunction with the SED1606
as a pair.
Since the SED1672 is so designed to drive LCD's over a wide range of voltages, and also the maximum potential
V
0
of its LCD drive bias voltages is isolated from V
DD
to allow the LCD driving bias voltages to be externally
generated optionally with a high accuracy, it can cope with a wide range of LCD panels.
The SED1672 is featured in its simple pad layout which is easy in mounting PC boards in addition to its selectable
bidirectional driver output sequence. It also has 68 LCD output segments of high pressure resistance and low
output impedance.
