Notes
1.
The operating supply current is measured during the STOP instruction executed immediately after RESET. All inputs
are driven HIGH and outputs are loaded with C

The parameter meets the I

C-bus specification for standard mode and fast mode devices.
Under steady state (non-transient) conditions, I
OL
must be externally limited as shown in Table 54. If I
OL
exceeds the
test conditions, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the
listed test conditions.

TESTING INPUT AND OUTPUT WAVEFORMS
.
AC test inputs are driven at 2.4 V for a logic 1 and 0.45 V for a logic 0. Timing measurements are taken at 2.0 V for a
logic 1 and 0.8 V for a logic 0. See Fig.46(a).
The float state is defined as the point at which the pin sinks 3.2 mA or sources 400
μ
A at the voltage test levels. See
Fig.46(b).
