General Description
Not recommended for new designs.
The HV66 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 blanking and polarity control of the
outputs. HVout1 is connected to the first stage of the shift register.
Data is shifted through the shift register on the logic rising
transition of the clock. A DIR pin causes data shifting counter-
clockwise 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), BL (blank) 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
transitions from high to low.
The blank signal, BL, when pulled low, will set all outputs to the
same state as the BP
OUT
. If this signal is left open then the BL
defaults to a high state.
