description
The 74ACT11139 is designed for use in high-performance memory-decoding or data-routing applications that
require very short propagation delay times. In high-performance memory systems, this decoder is used to
minimize the effects of system decoding.
The 74ACT11139 is composed of two individual 2-line to 4-line decoders in a single package. The active-low
enables (1G or 2G) can be used as data lines in demultiplexing applications. This decoder/demultiplexer
features fully buffered inputs, each of which represents only one normalized load to its driving circuit.
The 74ACT11139 is characterized for operation from –40°C to 85°C.
