General Description
The HV574 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 printer applications. It can also be used in any application
requiring multiple output high-voltage current sour-cing and sinking
capability such as driving plasma panels, vacuum fluorescent
displays, or large matrix LCD displays.
The device has 4 parallel 20-bit dynamic shift registers, permitting
data rates 4X the speed of one (they are clocked together). There
are 80 static 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 VDD. A data output buffer
is provided for cascading devices. This output reflects the current
status of the last bit of the shift register (HVOUT80). 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 (latch enable) input is high. The
data in the latches is stored when LE is low.
