【选型】国产模拟信号多路复用器芯片可PTP替代MC14051BDTR2G,静态电流仅1mA
针对于目前中美贸易战争影响以及国产化替代需求,国内芯片的崛起,很多被动器件芯片也被广泛使用。某些客户之前一直使用的安森美的MC14051BDTR2G用于安全光栅项目上。考虑到上述问题,在寻找一款可pin to pin替换安森美MC14051BDTR2G的国产模拟信号多路复用器芯片。
以下介绍一款圣邦微的SGM48751YS16G/TR,图1为两个产品的性能参数对比:
从图1 可以明显看出两者之间的差异,下面来看看管脚定义对比:
通过以上两个产品各方面的对比,可以看出:
1、圣邦微SGM48751YS16G/TR在静态电流-TYP方面具有一定优势,仅为1mA,低功耗,更省电;
2、封装相同,可实现pin to pin替换,设计电路时无需改板,大大减少验证时间;
3、圣邦微SGM48751YS16G/TR的工作温度最高只能达到85℃,但是用于消费类和工业类完全满足所需的工作标准。
圣邦微的SGM48751YS16G/TR属于国产器件,同类产品对比具有更好的性能及价格优势,可缓解缺芯市场危机,后续供货稳定。

安全光栅光幕可以互相替代?
光幕是机械安全领域安全隔离常用的装置。该用光幕的地方,错用了光栅,可能安全距离不够造成机械伤害。可以使用光栅的地方,选择了光幕,成本变高了,而且造成资源浪费。掌握一招,你也可以变身安全专家。安全设计靠谱,项目成本可控,场地空间优化,都轻松拿捏。安全光幕和光栅作为电敏保护器件,在标准里是不做区分的,只是光束间距不同,适用不同场景。
