74LVQ138数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

General Description
The LVQ138 is a high-speed 1-of-8 decoder/demultiplexer.
This device is ideally suited for high-speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three LVQ138 devices or a 1-of-32 decoder using four LVQ138 devices and one inverter.

特性 Features

■ Ideal for low power/low noise 3.3V applications
■ Guaranteed simultaneous switching noise level and
   dynamic threshold performance
■ Improved latch-up immunity
■ Guaranteed incident wave switching into 75Ω
■ 4kV minimum ESD immunity
■ Demultiplexing capability
■ Multiple input enable for each expansion
■ Active LOW mutually exclusive outputs

简介

74LVQ138属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的74LVQ138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。
