ADM3202ARNZ from Analog Devices, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive terminal of external charge pump capacitor C1 (0.1 µF, up to 47 µF). Connected between C1+ and C1- to support the +3.3 V to +6.6 V voltage doubler.
2 V+ power_out Internally generated positive supply, +6 V nominal (typ +6.6 V). Bypass to VCC (or to GND) with a 0.1 µF capacitor (C3, 6.3 V rated).
3 C1- passive Negative terminal of external charge pump capacitor C1 (0.1 µF, up to 47 µF). Paired with C1+ for the voltage doubler stage.
4 C2+ passive Positive terminal of external charge pump capacitor C2 (0.1 µF, up to 47 µF). Connected between C2+ and C2- to support the +6.6 V to -6.6 V voltage inverter.
5 C2- passive Negative terminal of external charge pump capacitor C2 (0.1 µF, up to 47 µF). Paired with C2+ for the voltage inverter stage.
6 V- power_out Internally generated negative supply, -6 V nominal (typ -6.6 V). Bypass to GND with a 0.1 µF capacitor (C4, 10 V rated).
7 T2OUT output Transmitter 2 driver output. RS-232/EIA-232 signal level (typically ±9 V, ±5.0 V min into a 3 kΩ load). Short-circuit current typically ±15 mA.
8 R2IN input Receiver 2 input. Accepts RS-232 signal levels (input range ±30 V). Includes an internal 5 kΩ pull-down resistor to GND and Schmitt-trigger hysteresis of 0.4 V.
9 R2OUT output Receiver 2 output. CMOS/TTL logic level output referenced to VCC (VOH ≥ VCC - 0.6 V at IOUT = -1 mA; VOL ≤ 0.4 V at IOUT = 1.6 mA). Inverted with respect to R2IN.
10 T2IN input Transmitter 2 driver input. Accepts 3.3 V TTL/CMOS logic levels (VINL ≤ 0.8 V, VINH ≥ 2.0 V). Internal ~5 µA pull-up to VCC forces a logic 1 when the input is left open.
11 T1IN input Transmitter 1 driver input. Accepts 3.3 V TTL/CMOS logic levels (VINL ≤ 0.8 V, VINH ≥ 2.0 V). Internal ~5 µA pull-up to VCC forces a logic 1 when the input is left open.
12 R1OUT output Receiver 1 output. CMOS/TTL logic level output referenced to VCC (VOH ≥ VCC - 0.6 V at IOUT = -1 mA; VOL ≤ 0.4 V at IOUT = 1.6 mA). Inverted with respect to R1IN.
13 R1IN input Receiver 1 input. Accepts RS-232 signal levels (input range ±30 V). Includes an internal 5 kΩ pull-down resistor to GND and Schmitt-trigger hysteresis of 0.4 V.
14 T1OUT output Transmitter 1 driver output. RS-232/EIA-232 signal level (typically ±9 V, ±5.0 V min into a 3 kΩ load). Short-circuit current typically ±15 mA.
15 GND power_in Ground reference. Must be connected to 0 V.
16 VCC power_in Power supply input, 3.3 V ±0.3 V (operating range 3.0 V to 5.5 V). Typical no-load supply current 1.3 mA; ~8 mA driving a 3 kΩ load. Decouple locally with 0.1 µF (C5).
