Although specified for TTL outputs, all ADSP-218xN outputs are CMOS-compatible and will drive to V
DDEXT
and GND, assuming no dc loads.

DD
measurement taken with all instructions executing from internal memory. 50% of the instructions are multifunction (Types 1, 4, 5, 12, 13, 14), 30%
are Type 2 and Type 6, and 20% are idle instructions.

Stresses greater than those listed above may cause permanent damage to the
device. These are stress ratings only. Functional operation of the device at these
or any other conditions greater than those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.

TFS1, A13–1, PF7–0) and Input only pins (CLKIN, RESET, BR, DR0, DR1,
PWD).
