The Intersil 82C84A is a high performance CMOS ClockGenerator-driver which is designed to service the requirementsof both CMOS and NMOS microprocessors such as the80C86, 80C88, 8086 and the 8088. The chip contains a crystalcontrolled oscillator, a divide-by-three counter and complete“Ready” synchronizaTIon and reset logic.StaTIc CMOS circuit design permits operaTIon with an externalfrequency source from DC to 25MHz. Crystal controlledoperaTIon to 25MHz is guaranteed with the use of a parallel,fundamental mode crystal and two small load capacitors.All inputs (except X1 and RES) are TTL compatible overtemperature and voltage ranges.Power consumption is a fraction of that of the equivalentbipolar circuits. This speed-power characteristic of CMOSpermits the designer to custom tailor his system design withrespect to power and/or speed requirements.
