SAE 81C90/91
Absolute Maximum Ratings
Ambient temperature under bias (
T
A): ..................................................................... – 40 to + 110 C
Storage temperature (
T
ST)........................................................................................ – 50 to + 150 C
Voltage on
V
CC pins with respect to ground (VSS) ..................................................... – 0.5 to + 6.0 V
Voltage on any pin with respect to ground (
V
SS) .................................................– 0.5 to VCC + 0.5 V
Input current on any pin during overload condition .................................................. – 10 to + 10 mA
Absolute sum of all input currents during overload condition ............................................. |100 mA|
Power dissipation..................................................................................................................... 0.5 W
Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability. During overload conditions (
V
IN > VCC or VIN < VSS) the
voltage on pins with respect to ground (
V
SS) must not exceed the values defined by the
Absolute Maximum Ratings.
Parameter Interpretation
The parameters listed in the following partly represent the characteristics of the SAE 81C90/91 and
partly its demands on the system. To aid in interpreting the parameters right, when evaluating them
for a design, they are marked in column “Symbol”:
DC (Device Characteristics):
The logic of the SAE 81C90/91 will provide signals with the respective timing characteristics.
SR (System Requirement):
The external system must provide signals with the respective timing characteristics to the
SAE 81C90/91.
