Pin Descriptions

Key: I = Input; O = output; P = power supply connection.

External Components

The ICS574 requires a minimum number of external components for proper operation. Decoupling capacitors of

0.1µF should be connected between VDD and GND on pins 4 and 5, as close to the device as possible. A series

termination resistor of 33

Ω may be used close to the pin for each clock output to reduce reflections.
