description
The 'AC14 devices contain six independent
inverters. The devices perform the Boolean
function Y = A.
The SN54AC14 is characterized for operation
over the full military temperature range of 55
C
to 125
C. The SN74AC14 is characterized for
operation from 40
C to 85
C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero
