74ls148 是8 线－3 线优先编码器，共有 54/74148 和 54/74ls148 两种线路结构型式，将 8 条数据线（0－7）进行 3 线(4-2-1)二进制（八进制）优先编码，即对最高位数据线进行译码。利用选通端（ei）和输出选通端（eo）可进行八进制扩展。

They provide priority decoding of the inputs to ensure that only the highest order data line is encoded. Both devices have data inputs and outputs which are active at the low logic level. The LS147 encodes nine data lines to four-line (8-4-2-1) BCD.
