Electrical Specifications
Note:
Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
External Components
The ICS615 requires a minimum number of external components for proper operation. A decoupling
capacitor of 0.1μF should be connected between VDD and GND on pins 7 and 2, as close to the ICS615
as possible. A series termination resistor of 33
may be used for the clock outputs. The normal use is with a
clock input into pin 3, with pin 4 left unconnected. For a crystal input, consult ICS/MicroClock.
