HI-8040
GENERALDESCRIPTION
The HI-8040 is a CMOS integrated circuit designed for high
voltage LCD display drive applications.
segmentsatvoltagesbetween+5and-30volts. Anoptional
negative converter can generate the negative display drive
voltage. Test inputsfacilitate opensand shortstesting. The
backplane frequency is checked and, as long as power is
available, the segments are shut "Off" if the frequency
becomestoolow.
It can drive 85
The HI-8040 is part of a family of display drivers which
control segment information in the same way.
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
segmentoutputs. Theshiftregisteris85bitslong.

The die is metal mask programmable to provide for various
package and/or cascade tap options.
