† Timing is over recommended temperature range. See Fig. 3 for control and I/O timing details.
‡ Typical figures are at 25°C and are for design aid only; not guaranteed and not subject to production testing.
Crosstalk measurements are for Plastic DIPS only, crosstalk values for PLCC packages are approximately 5dB better.
