External Components
The ICS548A-03 requires a minimum number of external components for proper operation. Decoupling capacitors
of 0.01µF should be connected between pins 3 and 5, as close to the device as possible. Connect pin 2 directly to
pin 3, and pin 6 directly to pin 5. A series termination resistor of 33Ω should be used on all clock outputs, as close
to the device as possible. Leave any unused clock outputs floating. There are no pull-up resistors on the input pins,
and they may be connected directly to VDD or ground.
