ID82C284

82C284 March 1997 Clock Generator and Ready Interface for 80C286 Processors Description The Intersil 82C284 is a clock generator/driver which provides clock signals for 80C286 processors and support components. It also contains logic to supply READY to the CPU from either asynchronous or synchronous sources and synchronous RESET from an asynchronous input with hysteresis. Features Generates System Clock for 80C286 Processors Generates System Reset Output from Schmitt Trigger Input - Improved Hysteresis Uses Crystal or External Signal for Frequency Source Dynamically Switchable between Two Input Frequencies Provides Local READY and MULTIBUS® READY Synchronization Static CMOS Technology Single +5V Power Supply Available in 18 Lead CerDIP Package Ordering Information PART NUMBER CD82C284-12 ID82C284-10 ID82C284-12 TEMP.
