General Description
The HV5408B is a low voltage serial to high voltage parallel
converter with push-pull 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 sourcing and sinking capabilities, such as driving plasma
panels, vacuum fluorescent, or large matrix LCD displays.
The HV5408B consists of a 32-bit shift register, 32 latches, and
control logic to enable outputs. Q1 is connected to the first stage
of the shift register through the Output Enable logic. Data is shifted
through the shift register on the low to high transition of the clock.
When viewed from the top of the package, the HV5408B 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.
