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).
