General Description
The HV507 is a low voltage serial to high voltage parallel con-
verter with 64 high voltage push-pull outputs. This device has
been designed for use as a printer driver for electrostatic applica-
tions. It can also be used in any application requiring multiple high
voltage outputs, 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, D
IOA
is Data In and D
IOB
is Data Out;
data is shifted from HV
OUT
64 to HV
OUT
1. When DIR is at logic high,
D
IOB
is Data In and D
IOA
is Data Out: data is then shifted from
HV
OUT
1 to HV
OUT
64. 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, BL, or the POL inputs. Transfer of data from
the shift register to the latch occurs when the LE is high. The data
in the latch is stored during LE transition from high to low.

Notes:
1. All voltages are referenced to GND.
2. Connection to all power and ground pads is required. Duty cycle is limited by
the total power dissipated in the package.
3. For operation above 25°C ambient derate linearly to 70°C at 26.7mW/°C.
