description/ordering information
The SN74HC139 device is designed for
high-performance memory-decoding or data-routing
applications requiring very short propagation delay
times. In high-performance memory systems, this
decoder can minimize the effects of system
decoding. When employed with high-speed
memories utilizing a fast enable circuit, the delay time
of this decoder 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 decoder is negligible.

The SN74HC139 device comprises two individual 2-line to 4-line decoders in a single package. The active-low
enable (G) 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.

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 51-7.
