General Description
The HV65 is a low-voltage serial to high-voltage parallel converter
with push-pull outputs. This device has been designed for use as
a driver circuit for LCD displays. It can also be used in any
application requiring multiple output high-voltage current sourc-
ing and sinking capabilities. The inputs are fully CMOS compat-
ible.
The device consists of a 32-bit shift register, 32 latches, and
control logic to perform the polarity select of the outputs. HVout1
is connected to the first stage of the shift register through the
polarity logic. Data is shifted through the shift register on the logic
low to high transition of the clock. A DIR pin causes data shifting
counterclockwise when grounded and clockwise when connected
to V
DD
. A data output buffer is provided for cascading devices.
This output reflects the current status of the last bit of the shift
register. Operation of the shift register is not affected by the LE
(latch enable) or the POL (polarity) inputs. Transfer of data from
the shift register to the latch occurs when the LE (latch enable)
input is high. The data in the latch is stored after LE transition from
high to low.
