Absolute Maximum Ratings
Stresses greater than those listed in this table may cause per-
manent damage to the device. These represent a stress rating
only. Operation of the device at these or any other conditions
above those specified in the operating sections of this specifi-
cation is not implied. Maximum conditions for extended peri-
ods may affect reliability

Notes:
1. Inputs FS1:0 have a pull-up resistor; Input OE# has a pull-down resistor.
2. Pins X1 and X2 each have a 34-pF capacitance. When used with a XTAL, the two capacitors combined load the crystal with 17 pF. If driving X1 with a
reference clock signal, the load capacitance will be 34 pF (typical).
