Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. The '46A, '47A, '48, 'LS47, and 'LS48 circuits incorporate automatic leading and/or trailing-edge zero-blanking control (RBI\ and RBO\). Lamp test (LT\) of these types may be performed at any time when the BI\/RBO\ node is at a high level.

The SN74LS47 are Low Power Schottky BCD to 7-Segment Decoder /Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. They offer active LOW, high sink current outputs for driving indicators directly.

74LS47是BCD-7 段数码管译码器 驱动器，74LS47 的功能用于将BCD 码转化成数码块中的数字，通过它来进行解码，可以直接把数字转换为数码管的数字，从而简化了程序，节约了 单片机 的IO开销。 因此是一个非常好的 芯片！ 但是由于目前从节约成本的角度考虑，此类芯片已经少用，大部分情况下都是用动态扫描数码管的形式来实现数码管显示。 译码器的逻辑功能是将每个输入的二进制代码译成对应的输出的高、低电平信号。 常用的译码器电路有二进制译码器、二--进 …
