MA17502
6.0 TIMING CHARACTERISTICS
This section provides the detailed timing specifications for
the MA17502. Figure 6 depicts the test load used to obtain
timing data. Figures 7 through 9 depict the timing waveforms
associated with various MA17502 signals. Table 7 provides
values for parameters specified in the timing waveforms. All
timing values provided in Table 7 are valid over the full military
temperature range (-55°C to +125°C), and are measured from
50% point to 50% point (50% of VDD supply voltage, unless
otherwise specified). Crosshatching in Figure 7 indicates either
a “don’t care” or indeterminate state.
