General Description
UM82C284 is a clock generator Idriver which provides clock signa Is for 80286 processors and support ponents. It also contains logic to supply READY to the CPU from
- Multibus is a patented bus of I NTE L either asynchronous or synchronous sources and synchronous RESET from an asynchronous input with hysteresis. It is fabricated in Si-Gate CMOS process.
