Other Parts Discussed in Thread: SN74LVC1G34
Tool/software:
Attached Image is my RS485 transceiver and this works with 5V. But as the reference design I can't pull up MCU pins to 5V cause I'm using stm32 MCU and the pins are 3.3V rated. How to pull up the pins to 5V without compromising the performance of the transceiver. The reason I can't go to a level shifter is that I want the flexibility to use SN65HVD1781DR IC as well which is 3.3V transceiver. Suggest me a simple design with a diode or voltage divider to fix this issue. Thanks.
