AMD Am8224

The Am8224 is a single chip Clock Generator/Driver for the Am9080A and 8080A CPU. It contains a crystal·controlled oscillator, a "divide by nine" counter, two high-level drivers and several auxiliary logic functions, including a power-up reset, status strobe and synchronization of ready. The Am8224 provides the designer with a significant reduction of packages used to generate clocks and timing for the Am9080A or 8080A for both commercial and military temperature range applications.
