HI-8040
GENERAL DESCRIPTION
The HI-8040 is a CMOS integrated circuit designed for high
voltage LCD display drive applications. It can drive 85
segments at voltages between +5 and -30 volts. An optional
negative converter can generate the negative display drive
voltage. Test inputs facilitate opens and shorts testing. The
backplane frequency is checked and, as long as power is
available, the segments are shut "Off" if the frequency
becomes too low.
The HI-8040 is part of a family of display drivers which
control segment information in the same way. Data is
serially clocked into the device and the data for all segment
outputs are latched in parallel when the Load input
transitions from high to low. With the Data Out from the shift
register available, devices may be cascaded to obtain more
segment outputs. The shift register is 85 bits long.
The die is metal mask programmable to provide for various
package and/or cascade tap options. Consult your Holt
Sales representative to explore the possibilities.
