specification is for the first LOW level seen by the SDAB/SCLB lines. V

is for the second and subsequent LOW levels seen by the
SDAB/SCLB lines.
[3] V
IL
for port A with envelope noise must be below 0.3V
CC(A)
for stable performance.
10. Dynamic characteristics
[1] Times are specified with loads of 1.35 k pull-up resistance and 57 pF load capacitance on port B, and 167 pull-up resistance and
57 pF load capacitance on port A. Different load resistance and capacitance will alter the RC time constant, thereby changing the
propagation delay and transition times.
[2] Pull-up voltages are V
CC(A)
on port A and V
CC(B)
on port B.
[3] Typical values were measured with V
CC(A)
= 3.3 V at T
amb
=25C, unless otherwise noted.
[4] The t
PLH
delay data from port B to port A is measured at 0.5 V on port B to 0.5V
CC(A)
on port A when V
CC(A)
is less than 2 V, and 1.5 V
on port A if V
CC(A)
is greater than 2 V.
[5] Typical value measured with V
CC(A)
=2.7V at T
amb
=25C.
[6] The proportional delay data from port A to port B is measured at 0.3V
CC(A)
on port A to 1.5 V on port B.
[7] The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
