Pin Assignment
Pin Descriptions
External Components
I CLK
A minimum number of external components are required for proper operation. A decoupling capacitor of
0.01 F should be connected between VDD on pin 7 and GND on pin 6, as close to the device as possible.
A 33 series terminating resistor may be used on each clock output if the trace is longer than 1 inch.
