Description
The UTS-413T is a low cost, low power, multi-mode infrared transceiver module in a ultra slimline form factor
ideally suited for portable wireless data communications and connectivity applications. The device consists
of an infrared emitting diode (IRED), a photodiode (PIN), and a low power control IC integrated into a single
package. Only a few external components are required to fully implement the module .
