Notes:
1. All clock outputs loaded with maximum lump capacitance test load specified in AC Electrical Characteristics section.
2. RC7104 logic inputs have internal pull-up resistors, except SEL100/66#.
3. X1 input threshold voltage (typical) is VDD/2.
4. The RC7104 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground.
Total load placed on crystal is 14pF; this includes typical stray capacitance of short PCB traces to crystal.
5. X1 input capacitance is applicable when driven X1 with an external clock source (X2 is left unconnected).
