General Description
The HV577 is a low-voltage serial to high-voltage parallel con-
verter with push-pull outputs. This device has been designed for
use as a driver for electroluminescent displays. It can also be used
in any application requiring multiple output high-voltage current
sourcing and sinking capability such as driving plasma panels,
vacuum fluorescent displays, or large matrix LCD displays.
The device has 4 parallel 16-bit shift registers, permitting data
rates 4X the speed of one ( they are clocked together). There are
also 64 latches and control logic to perform the polarity select and
blanking of the outputs. HVout1 is connected to the first stage of
the first shift register through the polarity and blanking logic. Data
is shifted through the shift registers on the logic low to high
transition of the clock. The DIR pin causes CCW shifting when
connected to GND, and CW shifting when connected to V
data output buffer is provided for cascading devices. This output
reflects the current status of the last bit of the shift register
(HV
(latch enable), BL (blanking), or the POL (polarity) inputs. Trans-
fer of data from the shift registers to the latches occurs when the
LE (latch enable) input is high. The data in the latches is stored
when LE is low.
For detailed circuit and application information, please refer
to application note AN-H3.
