Quiet Power
An isolated power for the internal processing logic. This input must be tied externally to all other chip
power inputs, except for V
Address Bus Power
An isolated power for sections of the address bus I/O drivers. This input must be tied externally to all other
chip power inputs, except for V
Data Bus Power
An isolated power for sections of the data bus I/O drivers. This input must be tied externally to all other
chip power inputs, except for V
Bus Control Power
An isolated power for the bus control I/O drivers. This input must be tied externally to all other chip power
inputs, except for V
Host Power
An isolated power for the HI08 I/O drivers. This input must be tied externally to all other chip power inputs,
