[1] LOW-level supply voltage.
[2] VIL specification is for the first LOW level seen by the SDAB/SCLB lines. VILc is for the second and subsequent LOW levels seen by the
SDAB/SCLB lines.
[3] VIL for port A with envelope noise must be below 0.3VCC(A) for stable performance.

[1] Times are specified with loads of 1.35 kΩ pull-up resistance and 57 pF load capacitance on port B, and 450 Ω 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 VCC(A) on port A and VCC(B) on port B.
[3] Typical values were measured with VCC(A) = 3.3 V at Tamb = 25 °C, unless otherwise noted.
[4] The tPLH delay data from port B to port A is measured at 0.5 V on port B to 0.3VCC(A) on port A.
[5] The proportional delay data from port A to port B is measured at 0.3VCC(A) on port A to 0.3VCC(B) on port B.
[6] The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
