DS26F31MQML-SP: 5V diff to 3.3V IO

Tom Hinckley25

Part Number: DS26F31MQML-SP
Other Parts Discussed in Thread: RM57L843, DS26LV32AQML, , DS26LV31QML

I am looking for RS-422 drivers and receivers that are Space Grade or Hi Rel parts for spacecraft. My issue is the driver/receiver I find are 5V, which the single end output of the receiver to the GPIO (RM57L843 micro) will be overvoltaged. Is there a receiver that handles a differential 5V signal and outputs to 3.3V? And driver, got to go the other way too.

Tom,
We do not have a 3.3V class V differential driver or receiver.
We do have 3.3V QML military ceramic devices.
The DS26LV32AQML is 3.3V receiver.
The DS26LV31QML is 3.3V driver. However, the 5V class V level driver DS26F31MQML-SP can be used as it has TTL level inputs.

I just noticed this DS26LV32AQML is a CFP package only.

There a LCCC package available?

Unfortunately, that is the only package offered.

I just checked the possibility of using LVDS (if that is an option for you).
All the space rated versions are in CFPs as well :

If you can use ceramic military, then there is a version in the LCCC for LVDS.

See the LVDS31 and LVDS32.
