74ACT11139中文资料双路 2 线路至 4 线路解码器/多路解复用器数据手册TI规格书

描述 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.
