1 / 11 page 1 ® 82C84A 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. Features • Generates the System Clock For CMOS or NMOS Microprocessors • Up to 25MHz Operation • Uses a Parallel Mode Crystal Circuit or External Frequency Source • Provides Ready Synchronization • Generates System Reset Output From Schmitt Trigger Input • TTL Compatible Inputs/Outputs • Very Low Power Consumption • Single 5V Power Supply • Operating Temperature Ranges - C82C84A . . . . . . . . . . . . . . . . . . . . . . . . . 0°C to +70°C - I82C84A . . . . . . . . . . . . . . . . . . . . . . . . .-40°C to +85°C - M82C84A . . . . . . . . . . . . . . . . . . . . . . .-55°C to +125°C • Pb-Free Plus Anneal Available (RoHS Compliant) Pinouts 82C84A (PDIP, CERDIP) TOP VIEW 82C84A (PLCC, CLCC) TOP VIEW Ordering Information PART NUMBER PART MARKING TEMP.

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. 10 11 12 13 14 15 16 17 18 9 8 7 6 5 4 3 2 1 VCC X2 EFI F/C OSC RES X1 GND ASYNC RESET CSYNC PCLK RDY1 READY RDY2 CLK AEN1 AEN2 4 5 6 7 8 910 11 12 13 3 2 1 20 19 15 14 18 17 16 RDY1 AEN2 NC READY RDY2 NC F/C EFI X2 ASYNC Data Sheet FN2974.3 December 6, 2005 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
