74ACT11139 (ACTIVE) Dual 2-Line to 4-Line Decoder/Demultiplexer

Dual 2-Line to 4-Line Decoder/Demultiplexer - 74ACT11139


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.
