MA40A5S Looking for connection plan info on MA40A5S

I’m looking for a connection diagram for the MA40A5S.
I’m currently working a project that will use ultrasonic wave to communicate. The message will be send in morse code format or something similar.
The framework of this project impose that I use a DSP to process my signal. Therefore I do not want to use a MA40A5R receiver, for it will eliminate the use of the signal processing.
I’m also wondering/searching if a normal microphone can “hear” the 40KHz produced.

Any insights?
ps. datasheet information on the MA40A5S is difficult to find!

Thanks

MA40A5S: positive pin is indicated with a small plastic ring.
Absolute polarity is not important, this is just to make sure units are in phase when multiple units are used.
Most microphones go up to 20KHz, so they are not suited for this purpose.
