description
The SNJ557202E is a CMOS integrated circuit designed to drive an LCD (liquid crystal display) for a dot matrix
STN (super twisted nematic). The common- (row) and segment- (column) driver functions are integrated on a
single chip.
In the common-driver mode, the outputs can be configured as one set of 160 output channels or as 2 sets of
80 output channels. In the segment-driver mode, the device can be configured for either four-bit-wide or
eight-bit-wide data. The duty cycle is over 1/400, and the output bias voltage range (V_EE) is from 20 V to 42 V
(45 V maximum).
This high-voltage CMOS Si gate device is available in a 197-pin TAB (tape automated bonding) package.
