74LS126A Datasheet, PDF (2/4 Pages) National Semiconductor (TI) – Quad TRI-STATE Buffer

Absolute Maximum Ratings (Note)
Supply Voltage
7V
Input Voltage
7V
Operating Free Air Temperature Range
0 C to a70 C
Storage Temperature Range
b65 C to a150 C
Note The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed The device should not be operated at these limits The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation
