Function
With state of the art submicron BiCMOS circuitry,
coupled with Infineon optoelectronic expertise, the
IRMS6115 and IRMT6115 outperforms its closest
rival. The transmit input is AC coupled, limiting trans-
mit pulse duration to 70 µs, preventing transmitter
damage and continuous LED output.
