General Description
The HV3418 is a low voltage serial to high voltage parallel
converter with push-pull outputs. This device has been designed
for use as a printer driver for inkjet applications. It can also be
used in any application requiring multiple output, high voltage,
low current sourcing and sinking capabilities.
The device consists of a 64-bit shift register, 64 latches, and
control logic to perform the polarity select and blanking of the
outputs. A DIR pin controls the direction of data shift through
the device. With DIR grounded, DIOA is Data-In and DIOB is
Data-Out; data is shifted from HVOUT64 to HVOUT1. When DIR
is at logic high, DIOB is Data-In and DIOA is Data-Out: data is
then shifted from HVOUT1 to HVOUT64. Data is shifted through
the shift register on the low to high transition of the clock. Data
output buffers are provided for cascading devices. 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 register to the latch occurs when the LE (latch enable) is
high. The data in the latch is stored during LE transition from
high to low.

Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect
device reliability. All voltages are referenced to GND.
Notes:
1. Connection to all power and ground pads is required. Duty cycle is
limited by the total power dissipated in the package.
2. For operation above 25°C ambiant derate linearly to maximum
operating temperature at 20mW/°C.
