HG3232AECM

HGSEMI · RS232 ICs · SOP-16

HG3232AECM from HGSEMI, in a SOP-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 capacitor C1. Connect a 0.1µF ceramic capacitor between C1+ and C1-.
2 V+ power_out Positive voltage generated by the internal charge pump (typically +2×VCC). Bypass to GND with a 0.1µF capacitor.
3 C1- passive Negative terminal of the voltage-doubler charge-pump capacitor C1.
4 C2+ passive Positive terminal of the inverting charge-pump capacitor C2. Connect a 0.1µF ceramic capacitor between C2+ and C2-.
5 C2- passive Negative terminal of the inverting charge-pump capacitor C2.
6 V- power_out Negative voltage generated by the internal charge pump (typically −2×VCC). Bypass to GND with a 0.1µF capacitor.
7 DOUT2 output RS-232 driver output for channel 2. ±15kV ESD protected; typical VOH ≈ +5.4V, VOL ≈ −5.4V into RL=3kΩ. Short-circuit protected to GND.
8 RIN2 input RS-232 receiver input for channel 2. ±15kV ESD protected; input range ±25V; input impedance 3-7kΩ; thresholds VIT+ ≤ 2.4V, VIT- ≥ 0.6V.
9 ROUT2 output TTL/CMOS receiver output for channel 2. Drives VCC-level logic; VOH ≥ VCC−0.6V at IOH=−1mA, VOL ≤ 0.4V at IOL=1.6mA. High when RIN2 is open.
10 DIN2 input TTL/CMOS driver input for channel 2. VIH ≥ 2.0V (VCC=3.3V) / 2.4V (VCC=5V); VIL ≤ 0.8V. Inverted through the driver to DOUT2.
11 DIN1 input TTL/CMOS driver input for channel 1. VIH ≥ 2.0V (VCC=3.3V) / 2.4V (VCC=5V); VIL ≤ 0.8V. Inverted through the driver to DOUT1.
12 ROUT1 output TTL/CMOS receiver output for channel 1. Drives VCC-level logic; high when RIN1 is open.
13 RIN1 input RS-232 receiver input for channel 1. ±15kV ESD protected; input range ±25V; input impedance 3-7kΩ.
14 DOUT1 output RS-232 driver output for channel 1. ±15kV ESD protected; typical ±5.4V swing into RL=3kΩ. Short-circuit protected to GND.
15 GND power_in Ground reference for the device and RS-232 signals.
16 VCC power_in Supply voltage input, +3.0V to +5.5V. Bypass with a 0.1µF ceramic capacitor close to the pin. Typical ICC ≈ 1mA (no load).
