DESCRIPTION
The ’AHC139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 2-V to 5.5-V VCC operation.
These devices are designed to be used in high-performance memory-decoding or data-routing applications
requiring very short propagation delay times. In high-performance memory systems, these decoders can be used
to minimize the effects of system decoding. When used with high-speed memories utilizing a fast enable circuit,
the delay times of these decoders and the enable time of the memory usually are less than the typical access
time of the memory. This means that the effective system delay introduced by the decoders is negligible.

(1) 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.
(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.
(4) The package thermal impedance is calculated in accordance with JESD 51-5
