## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R1IN | input | ±15kV ESD-protected RS-232 receiver 1 input with internal 5K pull-down (input range ±15V). |
| 2 | R2IN | input | ±15kV ESD-protected RS-232 receiver 2 input with internal 5K pull-down (input range ±15V). |
| 3 | R3IN | input | ±15kV ESD-protected RS-232 receiver 3 input with internal 5K pull-down (input range ±15V). |
| 4 | T1OUT | output | ±15kV ESD-protected RS-232 driver 1 output, short-circuit protected to ground. |
| 5 | T2OUT | output | ±15kV ESD-protected RS-232 driver 2 output, short-circuit protected to ground. |
| 6 | T3OUT | output | ±15kV ESD-protected RS-232 driver 3 output, short-circuit protected to ground. |
| 7 | T3IN | input | TTL/CMOS driver 3 input referenced to VL; connect to GND or VL if unused. |
| 8 | T2IN | input | TTL/CMOS driver 2 input referenced to VL; connect to GND or VL if unused. |
| 9 | T1IN | input | TTL/CMOS driver 1 input referenced to VL; connect to GND or VL if unused. |
| 10 | R3OUT | output | TTL/CMOS receiver 3 output referenced to VL; high-Z in shutdown. |
| 11 | R2OUT | output | TTL/CMOS receiver 2 output referenced to VL; high-Z in shutdown. |
| 12 | R1OUT | output | TTL/CMOS receiver 1 output referenced to VL; high-Z in shutdown. |
| 13 | STATUS | output | TTL/CMOS output that indicates whether valid RS-232 levels are present at R1IN, R2IN or R3IN (low when none). |
| 14 | SHUTDOWN | input | TTL/CMOS input; driven low it shuts down the device (drivers tri-stated, charge pump disabled), high gives normal operation. |
| 15 | ONLINE | input | TTL/CMOS input; low enables Auto On-Line mode, high disables it. |
| 16 | C1- | passive | Negative terminal of the voltage doubler charge pump capacitor (0.1µF for 3.0V to 3.6V VCC). |
| 17 | GND | power_in | Ground. |
| 18 | VL | power_in | Logic I/O supply, 1.65V to 5.5V and not greater than VCC. |
| 19 | VCC | power_in | Power supply, 3.0V to 5.5V. |
| 20 | V+ | power_out | Regulated positive (+5.5V) charge pump rail, needs a storage capacitor. |
| 21 | C1+ | passive | Positive terminal of the voltage doubler charge pump capacitor. |
| 22 | C2+ | passive | Positive terminal of the inverting charge pump capacitor. |
| 23 | C2- | passive | Negative terminal of the inverting charge pump capacitor. |
| 24 | V- | power_out | Regulated negative (-5.5V) charge pump rail, needs a storage capacitor. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
