* Output timing is specified for a valid signal measured at the pin. Timing is specified driving an unterminated
30- transmission line with a length characterized by a 2.5-ns one-way propagation delay. Buffer output
impedance is typically 30 ; the buffer specifications include approximately 5 ns for the signal to propagate
the length of the transmission line and back.
