В® General Description The HV57009 is a low-voltage serial to high-voltage parallel
converter with P-channel open drain outputs. This device has been
designed for use as a driver for plasma panels.
The device has two parallel 32-bit shift registers, permitting data
rates twice the speed of one (they are clocked together). There
are also 64 latches and control logic to perform the blanking of
the outputs. HVOUT1 is connected to the first stage of the first shift
register through the blanking logic. Data is shifted through the
shift registers on the logic low to high transition of the clock. The
DIR pin causes CCW shifting when connected to VSS, and CW
shifting when connected to VDD. A data output buffer is provided
for cascading devices. This output reflects the current status of the
last bit of the shift register (HVOUT64). Operation of the shift register …
