GM3232ETA from GATEMODE, in a TSSOP-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 the voltage-doubler charge-pump flying capacitor C1 (0.1µF typical at 3.3V; 0.047µF at 5V). Connect to C1- through the external capacitor. |
| 2 | V+ | power_out | Positive voltage generated by the internal charge pump (roughly +2×VCC). Bypass to GND with a 0.1µF-0.33µF capacitor (C3). |
| 3 | C1- | passive | Negative terminal of the voltage-doubler charge-pump flying capacitor C1. Pairs with C1+ (pin 1). |
| 4 | C2+ | passive | Positive terminal of the inverting charge-pump flying capacitor C2 (0.1µF at 3.3V; 0.33µF at 5V). Connect to C2- through the external capacitor. |
| 5 | C2- | passive | Negative terminal of the inverting charge-pump flying capacitor C2. Pairs with C2+ (pin 4). |
| 6 | V- | power_out | Negative voltage generated by the internal inverting charge pump (roughly -2×VCC). Bypass to GND with a 0.1µF-0.33µF capacitor (C4). |
| 7 | DOUT2 | output | RS-232 driver #2 output. Swings between V+ and V- (typical ±5V into 3kΩ) and drives the RS-232 connector. Inverted from DIN2. |
| 8 | RIN2 | input | RS-232 receiver #2 input. Tolerates ±25V with a 3-7kΩ (typ 5kΩ) internal input resistance; thresholds 0.6-2.4V. |
| 9 | ROUT2 | output | TTL/CMOS receiver #2 output. Drives high (VCC-0.1V) when RIN2 is low or floating, low when RIN2 is high. |
| 10 | DIN2 | input | TTL/CMOS driver #2 input. VIH ≥ 2.0V (VCC=3.3V) or 2.4V (VCC=5V); VIL ≤ 0.8V. Feeds the RS-232 driver that outputs on DOUT2. |
| 11 | DIN1 | input | TTL/CMOS driver #1 input. VIH ≥ 2.0V (VCC=3.3V) or 2.4V (VCC=5V); VIL ≤ 0.8V. Feeds the RS-232 driver that outputs on DOUT1. |
| 12 | ROUT1 | output | TTL/CMOS receiver #1 output. Drives high (VCC-0.1V) when RIN1 is low or floating, low when RIN1 is high. |
| 13 | RIN1 | input | RS-232 receiver #1 input. Tolerates ±25V with a 3-7kΩ (typ 5kΩ) internal input resistance; thresholds 0.6-2.4V. |
| 14 | DOUT1 | output | RS-232 driver #1 output. Swings between V+ and V- (typical ±5V into 3kΩ) and drives the RS-232 connector. Inverted from DIN1. |
| 15 | GND | power_in | Ground reference for the device and charge-pump return. |
| 16 | VCC | power_in | Positive supply, +3.0V to +5.5V (absolute max +6V). Bypass to GND with a 1µF capacitor close to the pin. |
