DESCRIPTION

GND
With state of the art submicron BiCMOS circuitry,
coupled with Infineon optoelectronic expertise, the
IRMS6400/IRMT6400 outperforms its closest rival.
Infineon has incorporated a mode selection pin that
toggles the device to operate in FIR (4 Mb/s) or
SIR/MIR (9.6 Kb/s to 1.152 Mb/s) mode. Its exter-
nal Shut Down (SD) feature cuts current consump-
tion to typically 0.01 µA. The transmit input is AC
coupled, limiting transmit pulse duration to 70 µs,
preventing transmitter damage and continuous
LED output. Mode select determines the data rate.
Low for 9.6 Kb/s to 1.152 Mb/s, high for 4 Mb/s.
*Pin 7 internally grounded
