MAX202EIN

HGSEMI · RS232 ICs · DIP-16

MAX202EIN 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 flying capacitor C1 (0.1 µF, 16 V). Connect to pin 3 (C1-) with a ceramic capacitor.
2 V+ power_out Positive charge-pump output, nominally +10 V (VCC-0.3 V to 14 V absolute max). Bypass to GND with a 0.1-µF capacitor (6.3 V or higher).
3 C1- passive Negative terminal of charge-pump flying capacitor C1 (0.1 µF). Connect to pin 1 (C1+).
4 C2+ passive Positive terminal of charge-pump flying capacitor C2 (0.1 µF, 16 V). Connect to pin 5 (C2-).
5 C2- passive Negative terminal of charge-pump flying capacitor C2 (0.1 µF). Connect to pin 4 (C2+).
6 V- power_out Negative charge-pump output, nominally -10 V (-14 V to 0.3 V absolute max). Bypass to GND with a 0.1-µF capacitor (16 V).
7 DOUT2 output RS-232 driver 2 output. Inverted TTL/CMOS input from DIN2; swings between V+ and V- (nominally ±10 V) with ≥30-V/µs slew rate. ±15-kV HBM ESD-protected RS-232 bus pin.
8 RIN2 input RS-232 receiver 2 input. Accepts ±30-V RS-232 levels with ~5-kΩ input resistance and hysteresis (VIT+ typ 1.7 V, VIT- typ 1.2 V). ±15-kV HBM ESD-protected RS-232 bus pin.
9 ROUT2 output TTL/CMOS receiver 2 output (inverted from RIN2). Swings from GND to near VCC; drives host UART RX.
10 DIN2 input TTL/CMOS driver 2 input. VIH ≥ 2 V, VIL ≤ 0.8 V; drives DOUT2 (inverted) to RS-232 levels.
11 DIN1 input TTL/CMOS driver 1 input. VIH ≥ 2 V, VIL ≤ 0.8 V; drives DOUT1 (inverted) to RS-232 levels.
12 ROUT1 output TTL/CMOS receiver 1 output (inverted from RIN1). Swings from GND to near VCC; drives host UART RX.
13 RIN1 input RS-232 receiver 1 input. Accepts ±30-V RS-232 levels with ~5-kΩ input resistance and hysteresis (VIT+ typ 1.7 V, VIT- typ 1.2 V). ±15-kV HBM ESD-protected RS-232 bus pin.
14 DOUT1 output RS-232 driver 1 output. Inverted TTL/CMOS input from DIN1; swings between V+ and V- (nominally ±10 V) with ≥30-V/µs slew rate. ±15-kV HBM ESD-protected RS-232 bus pin.
15 GND power_in Device ground / signal reference for all voltages.
16 VCC power_in +5-V supply input (recommended 4.5 V to 5.5 V, absolute max 6 V). Typical ICC ≈ 8 mA (no load, 15 mA max). Bypass to GND with at least 0.1 µF.

CAD (KiCad official)

  • Symbol: MAX202EIN
  • Footprint: Package_DIP:DIP-16_W7.62mm
  • 3D model: DIP-16 (KiCad packages3D, STEP)
  • 3D model files: max202ein-etched.step / max202ein-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max202ein.step / max202ein.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
max202ein.step 505 KB You want the bare part, or you mark your own boards.
max202ein-etched.step 2.1 MB You want the part with MAX202EIN already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 553 faces against 284 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HGSEMI datasheet (13 pp, sha256 d669a5a448fb5d49, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
