THVD2412V: RS422 Full duplex configuration

Juan Antonio López López
Prodigy 10 points

Part Number: THVD2412V

Hello, 

I have a question regarding the full duplex configuration on the THVD2412V. 

In the datasheet, "7.4 Device Functional Modes" paragraph, it is said:

When the driver enable pin, DE, is logic high (H), the differential output A/Y and B/Z follow the logic states at data input D.

This seems a little bit confusing because AB is described as receiver pair, so it should not follow D (driver). 

As far as I know in a full duplex configuration driver pair and receiver pair are independent lines so they are not following the same.

    Hi Juan,

    You are correct. The output pins become enabled when DE is set high. Output pins refer to Y/Z and not A/B (these are receiver pins as you rightfully called out).

    The A/B pins are called out because this device shares the same datasheet as the half duplex devices that end in THVD24X0 which do not have a Y/Z pin.
