PIN FUNCTION DESCRIPTIONS
Pin
No. Mnemonic Function
1 GND Ground Pin. Must be connected to 0 V.
2 C1– Negative Terminal of C1 (if C1 is Polarized
Capacitor).
3 V– Internally Generated Negative Supply Voltage.
4T
IN
Driver Input (3 V to 5 V TTL/CMOS
Logic Levels).
5R
OUT
Receiver Output (3 V to 5 V TTL/CMOS
Logic Levels).
6R
IN
Receiver Input (EIA-232 Signal Levels).
7T
OUT
Driver Output (EIA-232 Signal Levels).
8 SD Shutdown Input. Logic 1 on this input puts
the ADM101E into low power shutdown mode.
9 C1+ Positive Terminal of Charge Pump Capacitor
(if C1 is Polarized Capacitor).
10 V
CC
