USING THE EVALUATION BOARD WITH A GENERIC LOGIC SIGNAL
PATTERN GENERATOR
2.3.1
Introduction
The HV583 128-Channel High-Voltage Driver IC Evaluation Board can be operated by
a generic logic signal pattern generator, or by any signal driver, via the J5 pin header
connector (pin header not installed).

The user must ensure the minimum DC and AC electrical parameters are achieved by
the signal pattern generator. For more information, refer to the HV583 data sheet
(DS20005461).
2.3.2
Operating the Evaluation Board
When operating the evaluation board with a generic logic signal pattern generator, the
VDD_PIC pin should not be powered on. The VDD_PIC pin is an optional power pin
used only for the PIC32 Starter Kit (DM320001).
In case a read operation is required for the signal driver, it is recommended to operate
the pattern generator at the same voltage potential as the evaluation board (V
DD
). If,
for instance, the signal pattern generator is operating at a lower voltage (e.g., 3.3V)
than that of the evaluation board (5.0V), this will cause the ESD protection diodes of
the signal generator to forward bias and possibly damage the board.

WARNING
If a read-back operation is required by the generic signal pattern generator (or
by any signal driver), the operational voltage level of the logic signals must be
equal to the voltage potential of the evaluation board (V
DD
).
