NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for all outputs = 80 pF.
3. Parts are guaranteed to operate down to 0 Hz.
4. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins.
5. For availability of other devices with this specification, please contact Philips sales office.
