Versions

• 8284A - 5-8MHz c:81
• 8284A-1 - 10MHz c:82

Note, the 8284A is not the same as the 8284. The non-A is older, the A is updated.

The 8284A is a single chip clock generator/driver for the iAPX 86, 88 processors. The chip contains a crystal controlled oscillator, a divide-by-three counter, complete MULTIBUS "Ready" synchronization and reset logic.

• Generates the System clock for the iAPX 86, 88 Processors [5 MHz, 8 MHz with 8284A 10 MHz with 8284A-1]
• Uses a Crystal or a TTL Signal for Frequency Source
• Provides Local READY and Multibus READY Synchronization
• 18-Pin Package
• Single +5V Power Supply
• Generates System Reset Output from Schmitt Trigger Input
• Capable of Clock Synchronization with Other 8284As
