ADM3222ARWZ

Analog Devices · RS232 ICs · SOIC-18-300mil

ADM3222ARWZ from Analog Devices, in a SOIC-18-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Receiver enable, active low: receiver outputs are enabled when low and three-stated when high.
2 C1+ passive External capacitor 1 connects between C1+ and C1-; 0.1 μF recommended, larger up to 47 μF can be used.
3 V+ power_out Internally generated positive supply (+6 V nominal).
4 C1- passive External capacitor 1 connects between C1+ and C1-; 0.1 μF recommended, larger up to 47 μF can be used.
5 C2+ passive External capacitor 2 connects between C2+ and C2-; 0.1 μF recommended, larger up to 47 μF can be used.
6 C2- passive External capacitor 2 connects between C2+ and C2-; 0.1 μF recommended, larger up to 47 μF can be used.
7 V- power_out Internally generated negative supply (−6 V nominal).
8 T2OUT output Transmitter (driver) 2 output at RS-232 signal levels (typically ±9 V).
9 R2IN input Receiver 2 input accepting RS-232 levels, with internal 5 kΩ pull-down to GND and ±30 V overvoltage protection.
10 R2OUT output Receiver 2 output at CMOS logic levels.
11 T2IN input Transmitter (driver) 2 input accepting TTL/CMOS levels.
12 T1IN input Transmitter (driver) 1 input accepting TTL/CMOS levels.
13 R1OUT output Receiver 1 output at CMOS logic levels.
14 R1IN input Receiver 1 input accepting RS-232 levels, with internal 5 kΩ pull-down to GND and ±30 V overvoltage protection.
15 T1OUT output Transmitter (driver) 1 output at RS-232 signal levels (typically ±9 V).
16 GND power_in Ground pin, must be connected to 0 V.
17 VCC power_in Power supply input (3.3 V ± 0.3 V).
18 SD input Shutdown control, active low: when low the charge pump is shut down and the transmitter outputs are disabled.
