a. AC characteristics apply for parallel output termination of 50 to V TT .
b. V CMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the V CMR range
c. Violation of the 1.0 ns maximum input rise and fall time limit will affect the device propagation delay, device-to-device skew, reference input
d. Output pulse skew is the absolute difference of the propagation delay times: | t pLH - t pHL |.
