VCC在1.8V或者2.8V是否可以正常工作。

Other Parts Discussed in Thread: SN74AHCT1G14

Hi Ti Tema:

我的应运如下:(SN74AHCT1G14)

我们现在需求是26M的时钟,幅度用2.8V或者1.8V分别测试效果。原先晶体出来是2.8V空载,加负载后,会到1.0V。因为晶体料件工艺变更导致无法使用。我们想通过在晶体后面先加一个buffer,然后再接负载。晶体输出接A端,负载接Y端。

SN74AHCT1G14使用需求:

我们现在测试VCC=2.8V时,A端输出的话是2.8V峰峰。但是看规格书,VCC建议是4.5~5.5,所以需要确认,VCC1.8V或者2.8V是否可以正常工作?
