Electrical Characteristics
The data in this chapter represents all known data prior to qualification and characteriza-
tion of the Z84C90 KIO device and is therefore subject to change. Additional electrical
characteristics can be found in the individual chapters of this document.
Absolute Maximum Ratings
Stresses greater than those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This rating is a stress rating only. Operation of the device at any
condition above those indicated in the operational sections of these specifications is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Standard Test Conditions
The DC Characteristics and Capacitance sections that follow apply to the following stan-
dard test conditions, unless otherwise noted. All voltages are referenced to GND (0V).
Positive current flows into the referenced pin.
Available operating temperature ranges are:
• S = 0°C to +70°C
• E = –40°C to +100°C
Voltage Supply Range: +5.0V ± 10%
All AC parameters assume a load capacitance of 100 pF, as shown in Figure 33. Add a
10 ns delay for each 50 pF increase in load up to a maximum of 200 pF for the data bus and
100 pF for the address and control lines. AC timing measurements are referenced to 1.5
volts (except for CLOCK, which is referenced to the 10% and 90% points.
