SN74AHC158D集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

SN74AHC158D属于集成电路（IC）的信号开关多路复用器解码器。由美国德州仪器公司制造生产的SN74AHC158D信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。

description/ordering information

These quadruple 2-line to 1-line data

selectors/multiplexers are designed for 2-V to

5.5-V VCC operation.

The ’AHC158 devices feature a common strobe

(G) input. When the strobe is high, all outputs are

high. When the strobe is low, a 4-bit word is

selected from one of two sources and is routed to

the four outputs. These devices provide inverted

data.
