GM3232ETA

GATEMODE · RS232 ICs · TSSOP-16

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.
