Pin configuration

ST3243EB, ST3243EC

4/16

Doc ID 8648 Rev 12

R5OUT

Fifth receiver output voltage

R4OUT

Fourth receiver output voltage

R3OUT

Third receiver output voltage

R2OUT

Second receiver output voltage

R1OUT

First receiver output voltage

R2OUTB

Non-inverting complementary receiver output, always active

for wake-up

INVALID

Output of the valid signal detector. Indicates if a valid RS-232

level is present on receiver inputs logic "1"

FORCEOFF

Drive low to shut down transmitters and on-board power

supply. This over-rides all automatic circuitry and FORCEON

FORCEON

Drive high to override automatic circuitry keeping transmitters

on (FORCEOFF must be high)

C1-

Negative terminal of voltage-charge pump capacitor

GND

Ground

VCC

Supply voltage

V+

5.5 V Generated by the charge pump

C1+

Positive terminal of voltage-charge pump capacitor
