Hi support team all.

Could you provide me the data of VIH,VIL,VOH,VOL at Vcc=3.3V?

Best regards,

Hi Higa-san,

Please refer to this FAQ/calculator: https://e2e.ti.com/support/logic-group/logic/f/logic-forum/793508/faq-what-method-is-best-used-for-estimating-specification-values-between-those-given-in-the-datasheet

Hi Xu1-san

Thank you for your prompt reply.

I have a question.

For example, when IOL = 6mA at VOL, it is only when VCC = 4.5V, and there are no specifications for other VCC voltages.
What should I do when VCC = 3.3V?

Regards,

Higa

Hi Higa-san,

It most likely won't change significantly. You can either use 6 mA or go a big lower like 5 -5.5 mA.
