V_CCA = 0.8V to 5.5V, V_CCB = 2.2V to 5.5V, GND = 0V, TA = –40°C to 85°C (unless otherwise noted)⁽¹⁾⁽²⁾⁽³⁾

(1) Times are specified with loads of 240 Ω ±1% and 400 pF ±10% on B-side and 240 Ω ±1% and 200 pF ±10% on A-side. Different load resistance and capacitance alter the rise time, thereby changing the propagation delay and transition times.

(2) Times are specified with A-side signals pulled up to V_CCA and B-side signals pulled up to V_CCB.

(3) Typical values were measured with V_CCA = 0.9 V and V_CCB = 2.5 V at T_A = 25°C, unless otherwise noted.

(4) T_TLH is determined by the pull-up resistance and load capacitance

(5)
EN should change state only when the global bus and the repeater port are in an idle state
