The HV583 contains four parallel 32-bit Shift registers. Each 32-bit Shift register fea-
tures two ports that can be set as either inputs or outputs by controlling the DIR pin, as
shown in the following list:
• setting the DIR pin high enables the DnA pins as inputs and the DnB pins as
outputs (counterclockwise input data)
• setting the DIR pin low configures DnB pins as inputs and DnA pins as outputs
(clockwise input data)
Shunt (zero Ohm) resistors are placed right after the pin header connectors (D1B to
D4B) to facilitate the adjustment of the Input registers in any desired manner.

Note:
The HV583 128-Channel High-Voltage Driver IC Evaluation Board comes
equipped with shunt resistors only on the DnB pins. Shunt resistors are not
installed on the DnA pins.
