DESCRIPTION
The Infineon IRMS5000 is an IrDA compliant infrared
data transceiver featuring state of the art BiCMOS cir-
cuitry. The Shut Down (SD) feature cuts current con-
sumption to typically less than 0.01 µA. The Shut Down
(SD) mode disables the transmit input and tri-states the
receiver output. The transmit input is AC coupled, limit-
ing transmit pulse duration to 70 µs, preventing trans-
mitter damage. This also provides integrated protection
for eye safety.
