MIC8030
High-Voltage Display Driver
General Description
The MIC8030 is a CMOS high voltage liquid crystal display
driver. Up to 38 segments can be driven from four CMOS level
inputs (CLOCK, DATA IN, LOAD and CHIP SELECT). The
MIC8030 is rated at 50V. Data is loaded serially into a shift
register, and transferred to latches which hold the data until
new data is received.
The backplane can be driven from external source, or the
internal oscillator can be used. If the internal oscillator is
used, the frequency of the backplane will be determined by an
external resistor and capacitor. The oscillator need not be
used if a DC output is desired.
