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.
