82C84A CMOS Clock Generator Driver The 82C84A is a high performance CMOS Clock Generatordriver which is designed to service the requirements of both CMOS and NMOS microprocessors such as the 80C86, 80C88, 8086 and the 8088. The chip contains a crystal controlled oscillator, a divide-by-three counter and complete “Ready” synchronization and reset logic. Static CMOS circuit design permits operation with an external frequency source from DC to 25MHz. Crystal controlled operation 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 over temperature and voltage ranges. Power consumption is a fraction of that of the equivalent bipolar circuits.
