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.
