description
The 74AC11139 circuit is designed to be used in high-performance memory-decoding or data-routing
applications requiring very short propagation delay times. In high-performance memory systems, this decoder
can be used to minimize the effects of system decoding. When employed with high-speed memories utilizing
a fast enable circuit, the delay times of this decoder and the enable time of the memory are usually less than
the typical access time of the memory. This means that the effective system delay introduced by the decoder
is negligible.
The 74AC11139 is composed of two individual 2-line to 4-line decoders in a single package. The active-low
enable input can be used as a data line in demultiplexing applications. This decoder/demultiplexer features fully
buffered inputs, each of which represents only one normalized load to its driving circuit.
The 74AC11139 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 maximum package power dissipation is calculated using a junction temperature of 150 C and a board trace length of 750 mils,
except for the N package, which has a trace length of zero.
