General Description
The HV57708 is a low voltage serial to high voltage
parallel converter with push-pull outputs. The device has
been designed for use as a driver for EL 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 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. HV
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 VDD. A data output buffer is
provided for cascading devices. This output reflects the
current status of the last bit of the shift register (HV
Operation of the shift register is not affected by the LE (latch
enable), BL (blanking), or the POL (polarity) inputs. Transfer
of data from the shift registers to the latches occurs when
the LE input is high. The data in the latches is stored when
the LE is low.
