GENERAL DESCRIPTION
The 82284 is a clock generator/driver which provides clock signals for iAPX 286 processors and support components. The device contains logic to supply READY to the CPU from either asynchronous or synchronous sources. It also generates a synchronous reset signal from an asynchro- nous input with hysteresis.
DISTINCTIVE CHARACTERISTICS
• Generates system clock for iAPX 286 processors
• Uses crystal or TTL signal for frequency source
• Provides local READY and MULTIBUS READY synchronization
• Generates system reset output from Schmitt Trigger input
• 18-pin package
• Single +5 V power supply
