(1) All typicals are given for: V_CC = +5.0V, T_A = +25°C.
(2) Channel-to-Channel Skew is defined as the difference between the propagation delay of the channel and the other channels in the
same chip with an event on the inputs.
(3) Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays.
(4) Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z_O = 50Ω, t_r ≤ 6 ns, and t_f ≤ 6 ns.
(5) C_L includes probe and jig capacitance.
