T1IN, T2IN, T3IN TTL/CMOS compatible transmitter Inputs. The VL voltage sets the input switching point.
6, 7, 8
T1OUT, T2OUT,
T3OUT
±15kV ESD Protected
, RS-232 level (nominally ±5.5V) transmitter outputs.
1, 2, 3, 4, 5
R1IN, R2IN, R3IN,
R4IN, R5IN
±15kV ESD Protected
, RS-232 compatible receiver inputs.
18, 17
R1OUT, R2OUT
TTL/CMOS level receiver outputs. Swings between GND and VL.
20,19
19
R1OUTB, R2OUTB TTL/CMOS level, noninverting, always enabled receiver outputs. Swings between GND and VL.
20
INVALID
Active low output that indicates if no valid RS-232 levels are present on any receiver input.
Swings between GND and VL.
21
FORCEOFF
Active low to shut down transmitters and on-chip power supply. This overrides any automatic
22
FORCEON
Active high input to override automatic powerdown circuitry thereby keeping transmitters
active. (FORCEOFF must be high). The VL voltage sets the input switching point.
22
EN
Active low receiver enable control. The VL voltage sets the input switching point.
21
SHDN
Active low input to shut down transmitters and on-board power supply, to place device in low
power mode. The VL voltage sets the input switching point.
