SD/Mode
The IRMS6409 and IRMT6409 are the IRMS6400
and IRMT6400 with an integrated shield to provide
extra EMI immunity. With state of the art submi-
cron BiCMOS circuitry, coupled with Infineon opto-
electronic expertise, the IRMS6409/IRMT6409
outperforms its closest rival. Infineon has incorpo-
rated a mode selection pin that toggles the device
to operate in high rate (4.0 Mb/s) or low rate
(9.6 Kb/s to 1.152 Mb/s) mode. Its external Shut
Down (SD) feature cuts current consumption to
typically 0.01 µA. The transmit input is AC coupled,
limiting transmit pulse duration to 70 µs, prevent-
ing transmitter damage and continuous LED out-
put. Mode select determines the data rate. Low for
9.6 Kb/s to 1.152 Mb/s, high for 4.0 Mb/s.
