74LVQ138T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

74LVQ138T属于集成电路（IC）的信号开关多路复用器解码器。由意法半导体集团制造生产的74LVQ138T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

The 74LVQ138 is a low voltage CMOS 3 TO 8 LINE DECODER (INVERTING) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications.
