6 0 V on BR, CLKIN Active (to force tristate condition).

7Although specified for TTL outputs, all ADSP-2111 outputs are CMOS-compatible and will drive to V

DD and GND, assuming no dc loads.

8Guaranteed but not tested.

9Applies to ADSP-2111 PGA and PQFP packages.

10Output pin capacitance is the capacitive load for any three-stated output pin.
