ELECTRICAL DATA

Absolute Maximum Ratings

Case Temperature Under Bias (TC)

0 Cto a85 C

Storage Temperature

65 Cto a150 C

Voltage on Any Pin

with Respect to Ground

05V to VCC a05V

Power Dissipation15W

Power and Frequency Requirements

The typical relationship between ICC and the fre-

quency of operation F is as follows

ICCtyp e 55a 5 F mA

where F is in MHz

When the frequency is reduced below the minimum

operating frequency specified in the AC Characteris-

tics table the internal states of the 80C187 may be-

come indeterminate The 80C187 clock cannot be

stopped otherwise ICC would increase significantly

beyond what the equation above indicates

NOTICE This is a production data sheet The specifi-

cations are subject to change without notice

WARNING Stressing the device beyond the ‘‘Absolute

Maximum Ratings’’ may cause permanent damage

These are stress ratings only Operation beyond the

‘‘Operating Conditions’’ is not recommended and ex-

tended exposure beyond the ‘‘Operating Conditions’’

may affect device reliability
