I Need same part for 24V to 5V and 5V to 24V logic converter. for I/O logic level translator/optocoupler.

Other Parts Discussed in Thread: UCC27624, UCC27536, TLV1704, ISO1212

I explained our detailed requirement.

1) I have 4 input signal are logic range has 5V (Input) that in to 24V logic (output) conversion required.

2) Other 4 input signal are logic range has 24V (Input) that in to 5V logic (output) conversion required.

Total 8 I/O's 4 are input to the board 1 to 2, remaining 4 are output to 1 to 2, for this two requirement we are planning for single part.

please check and let know if any part is available.

Hi Sivakumar,

No, we do not have a device that can translate up to 24 V. Do you have a part number for the optocoupler you are trying to drive?

Logic does not go above 18 V.

To translate up at high speed, you can use a gate driver (e.g., UCC27536, UCC27624) as a buffer.

To translate up or down at low speed, you can use any comparator (e.g., TLV1704) with the middle of the input voltage range as reference voltage.

I don't have, Please suggest some circuit with optocoupler for this drive.

With two different it is possible right.

1) I got 24V to 5V logic conversion part ISO1212.

2) 5V to 24V logic conversion it is possible suggest any other part.

Hi Sivakumar,

The products I support will not work in this application, I can't help you with any part selections. You may explore the parts Clemens mentioned, but support will have to come from their respective e2e forums.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
