SN74LVC139A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

This dual 2-line to 4-line decoder/demultiplexer is designed for 1.65-V to 3.6-V VCC operation.
The 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 decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its driving circuit.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
