Would someone please suggest a good alternative to the H-bridge driver NJM2670E3 used in the Port-O-Rotary? A different footprint or pinout is fine because I’m drawing up my own board.

While I don’t have alternate suggestions; there is some stock at some places [https://octopart.com/njm2670e3-new+japan+radio-468259](https://octopart.com/njm2670e3-new+japan+radio-468259)

I’d much rather avoid doing that because I’d like for this design to be viable for several years.

I thought I found something usable with the MP6610 from Monolithic Power, but it seems that this one is only capable of swinging between +55V and 0V, not +55V+ and -55V. Still looking…
