MAX4936, MAX4937, MAX4938, MAX4939
Octal high-voltage transmit/receive switchesIntegrated T/R switches significantly reduce component count while reducing power
- Integrated solution reduces system component count, saving space and improving system reliability
- Consumes less system power, allowing design flexibility in ultra-portable applications
- Integrated diodes protect the IC from high-voltage signals while in “receive mode”

its so small :p
It is an ultrasound T/R switch. Wouldn’t use it for level translation.
