&lt;p&gt;你好，&lt;/p&gt;
&lt;p&gt;我们有一种应用场景需要选一款开关或多路复用器，用2片&amp;rdquo;开关&amp;ldquo;芯片实现对&lt;span style="text-decoration:underline;"&gt;被测芯片&lt;/span&gt;8路并行&amp;nbsp; 恒流源、恒压源二选一切换。&lt;/p&gt;
&lt;p&gt;这要求&amp;ldquo;开关&amp;rdquo;导通时具备双向通流能力，并且&amp;ldquo;开关&amp;rdquo;供电3.3V情况下（始终供电不会断电），在&amp;ldquo;开关&amp;ldquo;关断时确保不会有&lt;u&gt;恒压源4V&lt;/u&gt;到&lt;u&gt;恒流源&lt;/u&gt;的漏电流。&lt;/p&gt;
&lt;p&gt;因为空间和双向电流限制无法选择继电器或负载开关，我们查找到了SN74CBTLV3245A这款芯片，看datasheet好像符合我们要求。但是资料没有对AB端电压和VCC电压关系的限制进行介绍（比如AB两端电压不能超过VCC+0.5V之类），我只在datasheet中看到VCC工作电压2.3V~3.6V，以及VCC和VI（不确定VI是只指OE电压还是 OE和AB端电压）不能超过4.6V。&lt;/p&gt;
&lt;p&gt;我现在想请你们帮忙确认，SN74CBTLV3245A在3.3V供电条件下，OE拉高至3.3V后，B端存在一个4V电源情况下，是否会出现B 到 A、VCC、OE漏电情况或损坏SN74CBTLV3245A的情况。&lt;/p&gt;
&lt;p&gt;是否可以推荐可以符合该使用场景的开关芯片或多路复用器&lt;/p&gt;</description></item><item><title>RE: SN74CBTLV3245A-Q1: 测试电路切换开关SN74CBTLV3245A选型可行性</title><link>https://e2echina.ti.com/thread/3914406?ContentTypeID=1</link><pubDate>Thu, 06 Aug 2026 06:53:01 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:fb280661-a0c8-4bcf-a011-651995e060c4</guid><dc:creator>Alice</dc:creator><slash:comments>0</slash:comments><comments>https://e2echina.ti.com/thread/3914406?ContentTypeID=1</comments><wfw:commentRss>https://e2echina.ti.com/support/switches-multiplexers/f/switches-multiplexers-forum/1087581/sn74cbtlv3245a-q1-sn74cbtlv3245a/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;您好，&lt;/p&gt;
