HGX3232AEIMT

HGSEMI · RS232 ICs · TSSOP-16

HGX3232AEIMT from HGSEMI, 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 C1P passive Positive terminal of the charge-pump flying capacitor C1 (typ. 0.1 µF) used by the internal doubler that generates VP from VCC.
2 VP power_out Regulated positive charge-pump output, nominally +5.5 V (VCC×2 clamped). Bypass to GND with a 0.1 µF ceramic capacitor. Absolute-max +7.0 V.
3 C1N passive Negative terminal of the charge-pump flying capacitor C1 (typ. 0.1 µF) for the internal voltage doubler.
4 C2P passive Positive terminal of the charge-pump flying capacitor C2 (typ. 0.1 µF) used by the internal inverter that generates VN from VP.
5 C2N passive Negative terminal of the charge-pump flying capacitor C2 (typ. 0.1 µF) for the internal voltage inverter.
6 VN power_out Regulated negative charge-pump output, nominally −5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor. Absolute-max range −0.7 V to +0.3 V referenced to GND (i.e. always negative in normal operation).
7 T2OUT output RS-232 driver 2 output. Swings between VP and VN (typ. ±5 V) to meet EIA/TIA-232 levels. ESD-protected to ±15 kV HBM, ±15 kV IEC61000-4-2 air-gap, ±8 kV IEC61000-4-2 contact.
8 R2IN input RS-232 receiver 2 input. Accepts ±20 V (abs-max) RS-232 line levels through an internal 5 kΩ terminating resistor to GND. ±15 kV ESD-protected.
9 R2OUT output Receiver 2 CMOS/TTL logic output. Rail-to-rail swing between GND and VCC; drives the host UART RX line.
10 T2IN input Driver 2 CMOS/TTL logic input. Inverted by driver 2 and level-shifted onto T2OUT at RS-232 levels. Absolute-max −0.3 V to +6.0 V.
11 T1IN input Driver 1 CMOS/TTL logic input. Inverted by driver 1 and level-shifted onto T1OUT at RS-232 levels. Absolute-max −0.3 V to +6.0 V.
12 R1OUT output Receiver 1 CMOS/TTL logic output. Rail-to-rail swing between GND and VCC; drives the host UART RX line.
13 R1IN input RS-232 receiver 1 input. Accepts ±20 V (abs-max) RS-232 line levels through an internal 5 kΩ terminating resistor to GND. ±15 kV ESD-protected.
14 T1OUT output RS-232 driver 1 output. Swings between VP and VN (typ. ±5 V) to meet EIA/TIA-232 levels. ESD-protected to ±15 kV HBM, ±15 kV IEC61000-4-2 air-gap, ±8 kV IEC61000-4-2 contact.
15 GND power_in Device ground reference for logic, receivers, and charge-pump reservoir capacitors.
16 VCC power_in Main supply, +3 V to +5.5 V (abs-max +6.0 V). Bypass to GND with a 0.1 µF ceramic capacitor close to the pin. Typical ICC is 0.5 mA.
