All input signals are specified with t
= t
= 5 ns (10% to 90% of V
) and timed from a voltage level of (V
IL
+ V
IH
)/2.
All specifications typical at –40°C to 85°C, +VA = +4.75 V to +5.25 V, +VBD = +2.7 V to +5.25 V.
All digital output signals loaded with 10-pF capacitors.
CONVST_QUAL is CONVST latched by a low value on CS (see
Figure 39
).
Reference figure indicated is only a representative of where the timing is applicable and is not exhaustive.
Quiet time zones are for meeting performance and not functionality.
