Product Overview:
The HV632 is a high voltage 80V, 32-channel with 256 gray-shades driver IC designed for
driving flat panel displays such as polymer liquid crystal (PLC), vacuum fluorescent (VF),
electrofluorescent and field emission displays. It is especially suitable for applications requiring
a high data rate up to 20MHz and operating at an output voltage range of 12V to 80V.
Using Supertex proprietary HVCMOS technology, the HV632 features full integration of low
voltage CMOS logic to support the pulse width modulation (PWM) conversion of 256 levels of
gray shading for higher display resolution and 32 high voltage CMOS outputs, each capable
of 80V operation as well as sourcing and sinking 4mA. The HV632 provides an 8-bit data bus
for fast moving display image and for fine 256-level gray-scale resolution of each display pixel.
It also features output polarity and blank functions that provide flexibility in output control.
The data latched in each of the 32-channel latches is compared twice to the content of an 8-bit
up and down counter, thus generating the pulse width that is proportional to the data latched
in every channel latch. The HV
input data width (8 bits) and counter clock speed (10 MHz).
