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 | RO | output | Receiver output. RO is high when A-B ≥ -50mV and low when A-B ≤ -200mV. RO is high (full fail-safe) when the A and B inputs are open, shorted, or terminated and undriven. High-Z when /RE is high. |+| 2 | /RE | input | Active-low receiver output enable. RO is enabled when /RE is low; RO is high-impedance when /RE is high. If not required, tie to GND directly or through a 1kΩ to 3kΩ resistor. VIH ≥ 2V, VIL ≤ 0.8V. |+| 3 | DE | input | Driver output enable. Driver outputs Y and Z are enabled when DE is high and are high-impedance when DE is low. If not required, tie to VCC through a 1kΩ to 3kΩ resistor. Driving both DE=0 and /RE=1 puts the part into shutdown mode. |+| 4 | DI | input | Driver input. A low on DI forces Y low and Z high; a high on DI forces Y high and Z low. Logic input thresholds VIH ≥ 2V, VIL ≤ 0.8V. |+| 5 | GND | power_in | Ground reference for the transceiver. |+| 6 | A/Y | bidirectional | ±15kV IEC61000 ESD protected RS-485/RS-422 non-inverting bus pin. Acts as the receiver non-inverting input when DE = 0; acts as the driver non-inverting output (Y) when DE = 1. Common-mode range -7V to +12V. |+| 7 | B/Z | bidirectional | ±15kV IEC61000 ESD protected RS-485/RS-422 inverting bus pin. Acts as the receiver inverting input when DE = 0; acts as the driver inverting output (Z) when DE = 1. Common-mode range -7V to +12V. |+| 8 | VCC | power_in | System power supply input, 3.0V to 3.6V. Bypass with a 0.1µF ceramic capacitor to GND close to the pin. Quiescent supply current 510µA typical (800µA max); shutdown current 10nA typical. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RENESAS |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `ISL3172EIBZ-TISL3172EIBZ`+- `ISL3172EIBZ-T`+- `ISL3172EIBZ-TISL3172EIUZ`++## CAD (KiCad official)++- Symbol: `ISL3172EIBZ-T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [RENESAS datasheet](docs/isl3172eibz-t-datasheet.pdf) (19 pp, sha256 `46582fa2933098c4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
