(1) All typical values are given for: V_CC = +5.0V, T_A = +25°C.
(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z_O = 50Ω, t_r and t_f (0%–100%) ≤ 1 ns for R_IN and t_r and t_f ≤ 6 ns
for EN or EN*.
(3) Channel-to-Channel Skew is defined as the difference between the propagation delay of one channel and that of the others on the same
chip with an event on the inputs.
(4) C_L includes probe and jig capacitance.
