HGX202EIN

HGSEMI · RS232 ICs · DIP-16

HGX202EIN from HGSEMI, in a DIP-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 charge-pump capacitor C1 (0.1 µF, 6.3 V). Used by the internal voltage doubler that generates V+ from VCC.
2 V+ power_out Positive charge-pump output (~+10 V typical, max 14 V). Requires a reservoir capacitor (0.1 µF, 16 V) to GND. Supplies the positive RS-232 driver rail.
3 C1- passive Negative terminal of charge-pump capacitor C1 (0.1 µF, 6.3 V) used by the internal voltage doubler.
4 C2+ passive Positive terminal of charge-pump capacitor C2 (0.1 µF, 16 V). Used by the internal voltage inverter that generates V- from V+.
5 C2- passive Negative terminal of charge-pump capacitor C2 (0.1 µF, 16 V) used by the internal voltage inverter.
6 V- power_out Negative charge-pump output (~-10 V typical, min -14 V). Requires a reservoir capacitor (0.1 µF, 16 V) to GND. Supplies the negative RS-232 driver rail.
7 DOUT2 output RS-232 line driver 2 output. Swings between V- and V+ (typ ±9 V, min ±5 V into 3-kΩ load). ±15-kV HBM ESD protected. Output resistance 300 Ω. Short-circuit output current ±10 mA typ, ±60 mA max.
8 RIN2 input RS-232 line receiver 2 input. Accepts ±30 V input range with 3-7 kΩ input resistance (5 kΩ typ). Positive threshold 1.7-2.4 V, negative threshold 0.8-1.2 V, hysteresis 0.5 V typ. ±15-kV HBM ESD protected.
9 ROUT2 output Receiver 2 TTL/CMOS-level output. VOH ≥ 3.5 V at IOH = -1 mA, VOL ≤ 0.4 V at IOL = 1.6 mA. Inverted with respect to RIN2; goes high when RIN2 is low or open.
10 DIN2 input Driver 2 TTL/CMOS-level input. VIH ≥ 2 V, VIL ≤ 0.8 V. Inverted with respect to DOUT2. Input range 0 to 5.5 V.
11 DIN1 input Driver 1 TTL/CMOS-level input. VIH ≥ 2 V, VIL ≤ 0.8 V. Inverted with respect to DOUT1. Input range 0 to 5.5 V.
12 ROUT1 output Receiver 1 TTL/CMOS-level output. VOH ≥ 3.5 V at IOH = -1 mA, VOL ≤ 0.4 V at IOL = 1.6 mA. Inverted with respect to RIN1; goes high when RIN1 is low or open.
13 RIN1 input RS-232 line receiver 1 input. Accepts ±30 V input range with 3-7 kΩ input resistance (5 kΩ typ). Positive threshold 1.7-2.4 V, negative threshold 0.8-1.2 V, hysteresis 0.5 V typ. ±15-kV HBM ESD protected.
14 DOUT1 output RS-232 line driver 1 output. Swings between V- and V+ (typ ±9 V, min ±5 V into 3-kΩ load). ±15-kV HBM ESD protected. Output resistance 300 Ω. Short-circuit output current ±10 mA typ, ±60 mA max.
15 GND power_in Ground reference (0 V). All voltages are referenced to this pin.
16 VCC power_in Supply voltage input. Recommended 4.5 V to 5.5 V (5 V nominal). Bypass to GND with at least 0.1 µF. Typical supply current 8 mA (15 mA max, no load).
