bipolar decoder
双极译码器
A device with eight or more outputs that is used to expand systems that use input ports, output ports, and memory components with an active low chip-select input. In very large systems, the decoder can be used in sets, with each decoder driving eight or more other decoders for arbitrary memory expansions.
