CMOS Clock Generator Driver
The Intersil 82C84A is a high performance CMOS Clock
Generator-driver 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. This speed-power characteristic of CMOS
permits the designer to custom tailor his system design with
respect to power and/or speed requirements.

*Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
