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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | DIP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `MAX202EIN`+- `MAX202EINMAX202ECN`+- `MAX202EINMAX202EIM/TR`+- `MAX202EINMAX202ECM/TR`+- `MAX202EINMAX202EIMT/TR`+- `MAX202EINMAX202ECMT/TR`++## CAD (KiCad official)++- Symbol: `MAX202EIN`+- Footprint: `Package_DIP:DIP-16_W7.62mm`+- 3D model: DIP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/max202ein-datasheet.pdf) (13 pp, sha256 `d669a5a448fb5d49`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
