Description
Clock input. Internal pull-up resistor.
Clock Output 1.
Clock Output 2.
Clock Output 3.
Clock Output 4.
Connect to ground.
Connect to +3.3 V or +5.0 V.
Output Enable. Tri-states outputs when low. Internal pull-up resistor.
Key: CI = clock input, I = input, O = output, P = power supply connection
External Components
A minimum number of external components are required for proper operation. A decoupling capacitor of
0.01 µF should be connected between VDD on pin 7 and GND on pin 6, and a 33 Ω terminating resistor
may be used on each clock output if the trace is longer than 1 inch.
