DESCRIPTION
IRMS6100/IRMT6100 is an IrDA compliant 1.152 Mb/s infrared data
transceiver. Its external Shut Down (SD) feature cuts current consump-
tion to typically less than 0.01 µA. The Shut Down (SD) mode disables
the transmit input and tri-states the receiver output with a 500 kΩ pull
up. The transmit input is AC coupled, limiting transmit pulse duration to
70 µs, preventing transmitter damage and continuous LED output which
also provides protection for eye safety.

• Battery & Power Management Features:
Selectable LED transmit power (Pin 7) makes it easy for designers to
use standard power mode (Pin 7=H) for 1 meter link or low power mode
(Pin7=L) for 20 cm link.
