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 | R | output | Receiver output. Drives logic-high when VID = VA - VB > VIT+ (typ -10 mV), logic-low when VID < VIT- (typ -130 mV). High-drive output (>25 mA typ @ VOL=1V) suitable for driving optically isolated interfaces. Full fail-safe: outputs high when bus is open, shorted, or idle. High-Z when /RE is high or open. |+| 2 | /RE | input | Receiver enable (active-low). Drive low to enable the receiver; drive high (or leave open) to place the R output in high-impedance. Logic input thresholds VIH ≥ 2 V, VIL ≤ 0.8 V; input current ±2 μA max. |+| 3 | DE | input | Driver enable (active-high). Drive high to enable the driver output onto A/B; drive low (or leave open) to place A/B in high-impedance. Logic input thresholds VIH ≥ 2 V, VIL ≤ 0.8 V; input current ±2 μA max. |+| 4 | D | input | Driver data input. When DE is high, a logic-high on D drives bus A high and B low; logic-low drives A low and B high. Logic input thresholds VIH ≥ 2 V, VIL ≤ 0.8 V; input current ±2 μA max. Floating D with DE=H results in driving bus high (internal pull-up behavior). |+| 5 | GND | power_in | Ground reference for the device. Connect to system ground. |+| 6 | A | bidirectional | Non-inverting RS-485 differential bus pin. Driver output when DE=H; receiver non-inverting input when /RE=L. Common-mode range -7 V to +12 V; absolute limits -9 V to +14 V (±100 V transient through 100 Ω). ±12 kV HBM / ±8 kV IEC contact / ±15 kV IEC air-discharge ESD protected. |+| 7 | B | bidirectional | Inverting RS-485 differential bus pin. Driver output when DE=H; receiver inverting input when /RE=L. Common-mode range -7 V to +12 V; absolute limits -9 V to +14 V (±100 V transient through 100 Ω). ±12 kV HBM / ±8 kV IEC contact / ±15 kV IEC air-discharge ESD protected. |+| 8 | VCC | power_in | Supply voltage input. Recommended operating range 3.0 V to 5.5 V; absolute max 7 V. Quiescent supply current 3 mA typical (both driver and receiver enabled). Bypass locally with a 0.1 μF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `TPT75176B-SO1RSO1R`+- `TPT75176B-SO1RVS1R`+- `TPT75176B-SO1RDF6R`++## CAD (KiCad official)++- Symbol: `TPT75176B-SO1R`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [3PEAK datasheet](docs/tpt75176b-so1r-datasheet.pdf) (10 pp, sha256 `e7813b3b66193828`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
