Note 1: Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
Note on the 14.32 MHz output : The actual output frequency from this clock is 14.3196 MHz, versus
14.31818 MHz that has been traditional. This output can be used as the input to digital chips providing
functions such as timing or keyboard, but it should NOT be used to drive a graphics PLL that is used for a
CRT display. Instead, use a 14.318MHz crystal as the input to the CRT graphics device.
