General Description
The HV507 is a low voltage serial to high voltage parallel
converter with 64 push-pull outputs. This device has been
designed for use as a printer driver for electrostatic 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, D_IOA is Data-In and D_IOB is
Data-Out; data is shifted from HV_OUT64 to HV_OUT1. When DIR
is at logic high, D_IOB is Data-In and D_IOA is Data-Out: data is
then shifted from HV_OUT1 to HV_OUT64. 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 is high. The data in
the latch is stored during LE transition from high to low.
