General Description
The HV5623 is a low-voltage serial to high-voltage parallel converter
with open drain outputs. This device has been designed for use as
a driver for AC-electroluminescent displays. It can also be used in
any application requiring multiple output high voltage current sinking
capabilities, such as driving inkjet and electrostatic print heads,
plasma panels, and vacuum fluorescent or large matrix LCD displays.
This device consists of a 32-bit shift register, 32 latches, and control
logic to perform the polarity selection and blanking of the outputs.
Data are shifted through the shift register on the high to low transition
of the clock. The HV5623 shifts in a clockwise direction when viewed
from the top of the package. 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 (blanking), or 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 when LE is low.
