DESCRIPTION
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
μ
A. The transmit input is AC
coupled, limiting transmit pulse duration to 70
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.
