PIN DESCRIPTION
NAME NO. I/O
C1+ 2 — Positive terminals of the voltage-doubler charge-pump capacitors
C2+ 5
C1– 4 — Negative terminals of the voltage-doubler charge-pump capacitors
C2– 6
DIN 11 I Driver input
DOUT 13 O RS-232 driver output
EN 1 I Low input enables receiver ROUT output. High input sets ROUT to high impedance.
FORCEOFF 16 I Automatic power-down control input
FORCEON 12 I Automatic power-down control input
GND 14 — Ground
INVALID 10 O Invalid output pin. Output low when all RIN inputs are unpowered.
RIN 8 I RS-232 receiver input
ROUT 9 O Receiver output
VCC 15 — 3-V to 5.5-V supply voltage
V+ 3 O 5.5-V supply generated by the charge pump
V– 7 O –5.5-V supply generated by the charge pump
