CD74HC153中文资料高速 CMOS 逻辑双路 4 输入多路复用器数据手册TI规格书

描述 Description

The ’HC153 and ’HCT153 are dual 4- to 1-line selector/multiplexers that select one of four sources for each sectionby the common select inputs, S0 and S1. When the enable inputs (1E\\, 2E\\) are HIGH, the outputs are in the LOW state.

特性 Features

• Common Select Inputs
• Separate Enable Inputs
• Buffered inputs and Outputs
• Fanout (Over Temperature Range)
• Bus Driver Outputs . . . . . . . . 15 LSTTL Loads
• Balanced Propagation Delay and Transition Times
• HC Types
• High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
• Direct LSTTL Input Logic Compatibility, VIL = 0.8V (Max), VIH = 2V (Min)
• CMOS Input Compatibility, Il 1µA at VOL, VOH

简介

CD74HC153属于集成电路（IC）的信号开关多路复用器解码器。由TI制造生产的CD74HC153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。
