NOTE A: All input pulses are supplied by a genertor having the following characteristics: tr or tf £ 1ns,
pulse repetition rate (PRR) = 0.5 Mpps, pulse wide = 500 ±10ns. CL includes instrumentation
and fixture capacitance within 0.06m of the D.U.T.
NOTE B: To verify input max signalling rate, the input signal transition time (tr/tf) should not
exceeds 1.25ns.
