(1) Times are specified with loads of 1.35-kΩ pull-up resistance and 50-pF load capacitance on the B-side and 167-Ω pull-up and 57-pF load capacitance on the A side. Different load resistance and capacitance alter the RC time constant, thereby changing the propagation delay and transition times.
(2) The proportional delay data from A to B-side is measured at 0.3 VCCA on the A side to 1.5 V on the B-side.
(3) The tPLH delay data from B to A side is measured at 0.4 V on the B-side to 0.5 VCCA on the A side when VCCA is less than 2 V, and 1.5 V on the A side if VCCA is greater than 2 V.
(4) pull-up voltages are VCCA on the A side and VCCB on the B-side.
(5) Typical values were measured with VCCA = VCCB = 3.3 V at TA = 25°C, unless otherwise noted.
(6) Typical value measured with VCCA = 2.7 V at TA = 25°C
