Although specified for T T L outputs, all ADSP-21msp58/59 outputs are CMOS-compatible and will drive to V
and GND, assuming no dc loads.
6
Idle refers to ADSP-21msp58/59 state of operation during IDLE instruction. Deasserted pins are driven to either V
DD
or GND. Refer to chart in back for lower
IDLE currents.

Current reflects the digital portion of device operating with no output loads and a 2 k
load on the analog output (VOUT
, VOUT
).
10
t
= 76.92 ns, CODEC active, 80% execution type 1 instructions, with random data. For typical figures for digital and analog supply currents, refer to “Power
Dissipation” section.
11
Guaranteed but not tested.
12
Output pin capacitance is the capacitive load for any three-stated output pin.
