General Description
The HV5630 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, 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 select and blanking of the outputs. Data
is shifted through the shift register on the high to low transition of the
clock. The HV5630 shifts in the 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 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 when
LE is low.
