All input signals are specified with tR = tF = 5 ns (10% to 90% of VDRIVE) and timed from a voltage level of 1.6 V. All timing specifications are with a 25 pF load capacitance. With a load capacitance greater than 25 pF, a digital buffer or latch must be used. See the Terminology section, Figure 25, and Figure 26. 2 The time required for the output to cross is 0.4 V or 2.4 V. Rev.
