PB8224 CLOCK GENERATOR AND DRIVER FOR 8080A PROCESSORS DESC RIPT ION The pPB8224 is a single chip clock generator and driver for 8080A processors.
The clock frequency is determined by a user specified crystal and is capable of meeting the timing requirements of the entire 8080A family of processors.
MOS and TTL level clock outputs are generated.
Additional logic circuitry of the !1I'B8224 provides signals for power-up reset, an advance status strobe and properly synchronizes the ready signal to the processor.
This greatly reduces the number of chips needed for 8080A systems.
The !1I'B8224 is fabricated using NEe's Schottky bipolar process.
FE ATU RES • Crystal Controlled Clocks • Oscillator Output for External Timing • MOS Level Clocks for 8080A Processor • TTL Level Clock for DMA Activities • Power-up Reset for 8080A Processor • Ready Synchronization • Advanced Status Strobe • Reduces System Package Count • Available in 16-pi...
