15 R5
OUT
Fifth receiver output voltage
16 R4
OUT
Fourth receiver output voltage
17 R3
OUT
Third receiver output voltage
18 R2
OUT
Second receiver output voltage
19 R1
OUT
First receiver output voltage
20 R2
OUTB
Non-inverting complementary receiver output, always active
for wake-up
21 INVALID
Output of the valid signal detector. Indicates if a valid RS-232
level is present on receiver inputs logic "1"
22 FORCEOFF
Drive low to shut down transmitters and on-board power
supply. This over-rides all automatic circuitry and FORCEON
23 FORCEON
Drive high to override automatic circuitry keeping transmitters
on (FORCEOFF
must be high)
