(1) All typical values are given for: VCC = +5.0V, TA = +25°C.
(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50Ω, tr and tf (0%–100%) ≤ 1 ns for RIN and tr and tf ≤ 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) CL includes probe and jig capacitance.
