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, vac-
uum 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. HV
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
(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.
