Maximum Ratings

(Above which the useful life may be impaired. For user guidelines, not tested)

Storage temperature ......................................................-65°C to +150ºC

Ambient Operating Temperature ....................................... 0°C to +70ºC

Supply Voltage to Ground Potential (VCC)..................... -0.3V to +7.0V

Inputs (Referenced to GND)................................... -0.5V to VCC +0.5V

Clock Output (Referenced to GND) ....................... -0.5V to VCC +0.5V

Soldering Temperature (Max of 10 seconds).................................260ºC

Note:

Stresses greater than those listed under MAXIMUM RATINGS

may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other

conditions above those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

External Components

The PI6C4512 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.1µF || 0.01µF

should be connected between each VDD and GND and placed as close to the chip as possible. A series termination resistor of 33Ω

may be used for clock outputs. If a crystal is used, it should be a fundamental mode, parallel resonant crystal. Crystal capacitors

should be connected from X1 to ground and from X2 to ground to according to the crystal specifications. The value of capacitors is

given by the following equation, where CL is the crystal load capacitance: Crystal caps (pF) = (CL -15) x 2.
