Although specified for T T L outputs, all ADSP-2173 outputs are CMOS-compatible and will drive to V
DD
and GND, assuming no dc loads.

0 V on
BR,
CLK IN Active (to force three-state condition).
9
Idle refers to ADSP-2173 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD
or GND. Current reflects
device operation with CLK OUT disabled.
10
Current reflects device operating with no output loads.
11
V
= 0.4 V and 2.4 V. For typical figures for supply currents, refer to “Power Dissipation” section.
12
See Chapter 9, of the
ADSP-2100 Family User’s Manual
for details.
13
Applies to T QFP and PQFP package types.
14
Output pin capacitance is the capacitve load for any three-state output pin.
