I am part of a team designing a prototype of an ultrasound system. We are very interested in the TX734, as we are already using many other TI ICs for our design. However, I have not been able to find any information about the TX734 aside from vague references in general documents. Is this part in production, and does it have available models for simulation?

If not, is there another TI part that can provide bipolar 100V pulses with a bandwidth of at least 3 MHz?
