Hello experts,
Ryo,
I'm sorry I'm not familiar with the audio terminology. It looks like AES/EBU is basically RS-422 signaling. If so, SN75ALS191 should work.
Is SPDIF single-ended TTL logic? What's the requirement about the RS-485/422 transceiver, like data rate, common mode range? The latest TI parts can be found in this e2e post.

Hao
Hello Hao-san,
Akashi-san,
Looking at the SN75ALS191's datasheet, I think the key specifications are: 5V supply, 20Mbps data rate, 2V Vod @ 100Ohm load (again I'm not sure if AES/EBU has other requirement like EMC/EMI). Given these spec, THVD1550 could be used to replace SN75ALS191. THVD1550 works with 50Mbps and +/-15V common mode range, and has integrated updated ESD protection. However it would be better to know the system requirement for recommending the device.

Hao
