Infrared transceiver pins

[tistn009]

Hi

I am working on a system with 4 IR transceivers on a microcontroller.
But i have a practical problem.
I assume i need 3 pins for every transceiver.
But on the microcontroller i only have 4 spare pins.
Is there a solution to connect all 4 of them anyway?

More information needed.

What are the pins on the IR transceivers and what kind of data are they carrying? A proposed schematic or block diagram would help.
