INPUT / OUTPUT PINS
either logic inputs or logic outputs. At power-up or after a
Clear Command, the pins default to inputs. They can be
individually configured as outputs as needed via the I/O
Control Command on the bus.

ADDRESSING
DBUS devices. If this device is connected in a daisy chain,
then it will receive its 4-bit address during initialization on the
bus.
TEST MODE
evaluation purposes. The test mode can only be entered if all
of the following conditions are true:
values to them can change the behavior of many of the pins
on the device, including the T
test mode. The test mode can be intermixed with other bus
commands to evaluate the behavior of internal circuit blocks.
TEST1 pin should be tied externally to AGND. The T
should be grounded when not in TEST mode.
The 33784 may be connected in a daisy chain to other
The 33784 can be configured in a special test mode for
• The TEST1 pin is at a logic high level
• The correct test mode command is sent to the device on
• One of the internal test mode registers is accessed
