Pin Description (continued)
TTL/CMOS RS-232 Receiver Output. For the MAX3130, drive IRMODE low to connect
R2OUT to the IR receiver output, and drive IRMODE high to connect R2OUT to the
RS-232 receiver output. For the MAX3131, R2OUT is always internally connected to the
RS-232 receiver output.

FUNCTION
NAME
—
IR Mode Control. Drive IRMODE low to connect R2OUT to the IR receiver output and
T2IN to the IR transmitter input. Driving IRMODE low also shuts down the RS-232
charge pump and puts the RS-232 transmitter outputs in a high-impedance state. Drive
IRMODE high to connect R2OUT to the RS-232 receiver output and connect T2IN to the
RS-232 transmitter input.
