MC74HC151A中文资料8 输入多路复用器数据手册ONSEMI规格书

描述 Description

The MC74HC151 is identical in pinout to the LS151. The device inputs are compatible with standard CMOS outputs with pullup resistors, they are compatible with LSTTL outputs. This device selects one of the eight binary Data Inputs, as determined by the Address Inputs. The Strobe pin must be at a low level for the selected data to appear at the outputs. If Strobe is high, the Y output is forced to a low level and the Y bar output is forced to a high level. The HC151 is similar in function to the HC251 which has 3-state outputs.

特性 Features

• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 A
• High Noise Immunity Characteristic of CMOS Devices
• These are PbFree Devices

应用 Application

• Desktop, Industrial

简介

MC74HC151A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MC74HC151A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。
