Note1: Applicable to input signals: S0, S1, OE and SSCG#
Note2: Applicable to Sdata, and Sclk.
Note3: Although internal pull-up resistors have a typical value of 250K, this value may vary between 200K and 500K.
Note4: All outputs load in accordance with table 1.
Note5: Although the device will reliably interface with crystals of a 17pF – 20pF C
L
range, it is optimized to interface
with a typical C
L
= 18pF crystal specifications.
