Note 1 The maximum capacitive loading of OSCOUT is given in Table 3-1 when the NS32CG16’s oscillator is driven with a crystal If a single phase clock source is
used OSCOUT should be left unconnected or loaded with no more than 5 pF of stray capacitance

4 5 1 Definitions
All the timing specifications given in this section refer to
0 8V or 2 0V on the rising or falling edges of all the signals
as illustrated in Figures 4-3 and 4-4 unless specifically stat-
ed otherwise The capacitive load is assumed to be 100 pF
on CTTL and 50 pF on all the other output signals
