LVTTL to RS422

Marlie on Dec 1, 2017

Hello, I want to convert 2 LVTTL signals to RS422 with the lowest delay possible.

Can anyone please suggest the best possible devices to achieve this.

Many thanks.

Hi Marlie,

Where is the LVTTL coming from? A microcontroller? Can you share the part number?

The ADM4168E takes standard CMOS input levels and outputs to RS-422:

The ADM4168E should be LVTTL compatible:
