C bus reset 25 ms (min)
35 ms (max)
t
RSDA
Minimum NTEST_IN/Reset_IN rising edge to SDA falling edge 2 μs

(1) Timing specifications are tested at the Serial Bus Input logic levels, V
IN(0)
= 0.3 × V
+
for a falling edge and V
IN(1)
= 0.7 × V
+
for a rising
edge when the SCL and SDA edge rates are similar.
(2) Typicals are at T
J

A
= 25°C and represent most likely parametric norm.
(3) Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not..
