Description
HV5308 and HV5408 are low-voltage serial to high-
voltage parallel converters with push-pull outputs.
These devices have been designed for use as a driver
for AC-electroluminescent displays. HV5308 / HV5408
can also be used in any application requiring multiple
output high-voltage, current sourcing, and sinking
capabilities such as driving plasma panels, vacuum flu-
orescent, or large matrix LCD displays.
These devices consist of a 32-bit shift register,
32 latches, and control logic to enable outputs. Data is
shifted through the shift register on the low-to-high tran-
sition of the clock. HV5308 shifts in the clockwise
direction, when viewed from the top of the package,
and HV5408 shifts in the counter-clockwise direction.
A data output buffer is provided for cascading devices.
This output reflects the current status of the last bit of
the shift register (32). Operation of the shift register is
not affected by the LE (latch enable) or the OE (output
enable) inputs. Transfer of data from the shift register
to the latch occurs when the LE input is high. The data
in the latch is retained when LE is low.
