General Description
The HV528 is a 200V, 16-channel serial to parallel converter.
The high voltage outputs and the backplane driver are
designed to source and sink ±1.0mA.
The high voltage outputs are controlled by a 16-bit serial shift
register, followed by a 16-bit latch. Data is shifted through
the shift registers during the low to high clock transition. A
data output buffer is provided for cascading multiple devices.
Data is transferred to the 16-bit latch when a logic level low is
applied to the LE input. Data is stored in the latch when LE is
high. Output states are controlled by the data in the latch and
by the POL pin.
