NOTES:
1. X = Logical 1 or logical O.
2. Not more than one output is to be allowed to
be ON at one time: When all timing inputs are
at a logical 1, two of the address inputs must
be at logical O.
Standard positive logic applies with the following
definitions used for specifying digital-level
signals:
LOW VOLTAGE = LOGICAL 0
HIGH VOLTAGE = LOGICAL 1
Absolute Maximum Ratings Over Operating
Case Temperature Range (unless otherwise
noted)
Supply voltage Vee (See Note 1) ........ 17V
Input voltage (See Note 2) .............. 5.5V
Operating case temperature range O'C to 70·C
Continuous total power dissipation
at (or below) 70'C case
temperature ..................... 800mV
Storage temperature range .. -65'C to 150'C
NOTES:
1. Voltage values are with respect to network
ground terminal.
2. Input signals must be zero or positive with
respect to network ground terminal.
