Other Parts Discussed in Thread: SN74LVC1G125, SN74LVC1G126
Hi,
The customer power sequence is as follows:
1. VCCA, OE=1.8V and VCCB=3.3V are applied
2. After 10s
3. Boots 1.8V processor and 3.3V processor
Customers want to lock B4 to High for 10s from the time 1.8V is applied to the OE until the processor starts.
Is there any good way?
Since there is an internal pull-up resistance as shown in the following material, do not I need to take any measures?https://www.ti.com/lit/an/scea054a/scea054a.pdf?ts=1656689448543&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTXS0104E&_ticdt=MTY4MzY5OTk3M3wwMTc5OWI5OGI4OGIwMDBjZTdhYjY4NzQ5NjM5MDMwNzMwMDI3MDZiMDA5Nzh8R0ExLjIuMTM1MTg0OTI4NS4xNjIxODEzMTQ4
Or should I install a pull-up resistance of more than 50kohm?
Best Regards,
