  "readme": "# TXS0108E 8-Bit Level Shifter Molecule\n\nAn Adom molecule breakout for the **Texas Instruments TXS0108E**, an 8-bit bidirectional voltage-level translator. Designed for the Adom machine-pin ecosystem with medium-pitch contacts.\n\n## Overview\n\nThe TXS0108E translates 8 channels bidirectionally between two voltage domains (VCCA: 1.2–3.6 V, VCCB: 1.65–5.5 V). This molecule breaks out all 8 data channels plus power and OE to Adom machine-pin contacts for plug-in use on baseboard layouts.\n\n| Parameter | Value |\n|-----------|-------|\n| IC | TXS0108ERGYR (TI, VQFN-20) |\n| Channels | 8 bidirectional |\n| VCCA range | 1.2 V – 3.6 V |\n| VCCB range | 1.65 V – 5.5 V |\n| Data rate | Up to 110 Mbps (push-pull) |\n| OE pin | Active-high output enable |\n\n## Pin Map\n\n| Contact | Signal | Side | Description |\n|---------|--------|------|-------------|\n| A1 | VCCA | Left | Low-voltage supply |\n| A2 | A1 | Left | Port A channel 1 |\n| A3 | A2 | Left | Port A channel 2 |\n| A4 | A3 | Left | Port A channel 3 |\n| A5 | A4 | Left | Port A channel 4 |\n| A6 | A5 | Left | Port A channel 5 |\n| A7 | A6 | Left | Port A channel 6 |\n| A8 | A7 | Left | Port A channel 7 (active low on silk) |\n| B1 | VCCB | Right | High-voltage supply |\n| B2 | B1 | Right | Port B channel 1 |\n| B3 | B2 | Right | Port B channel 2 |\n| B4 | B3 | Right | Port B channel 3 |\n| B5 | B4 | Right | Port B channel 4 |\n| B6 | B5 | Right | Port B channel 5 |\n| B7 | B6 | Right | Port B channel 6 |\n| B8 | B7 | Right | Port B channel 7 |\n| GND | GND | Bottom-left | Ground |\n| OE | OE | Bottom-right | Output enable (active high, pulled high via 100 kΩ) |\n\n## Components\n\n| Ref | Value | Package | Library |\n|-----|-------|---------|---------|\n| U4 | TXS0108ERGYR | IC_TXS0108ERGYR | TXS0108ERGYR |\n| C3 | 100 nF | 0603 (CAPC1608X85) | Adom JLCPCB Library |\n| C4 | 100 nF | 0603 (CAPC1608X85) | Adom JLCPCB Library |\n| R5 | 100 kΩ | 0603 | Adom JLCPCB Library |\n| A1–A8 | Machine pin contact | CONTACT_MED | Adom_Library_Master |\n| B1–B8 | Machine pin contact | CONTACT_MED | Adom_Library_Master |\n| GND, OE, VCCA, VCCB | Machine pin (short) | MACH_PIN_MED_SHORT | Adom_Library_Master |\n\n## Design Notes\n\n- **Bypass caps** (C3, C4) are 100 nF ceramic on both VCCA and VCCB rails, placed close to the IC\n- **OE pull-up** (R5) is 100 kΩ to VCCB — output enable defaults to active (high) so the level shifter is always on unless OE is driven low\n- **Bidirectional auto-direction sensing** — no direction pin needed; the TXS0108E detects which side is driving\n- **Machine pin contacts** use the medium-pitch Adom contact system for plug-in integration with baseboards\n\n## Fusion 360 Cloud Location\n\n```\nMain > Molecules > XRP > TimeOfFlightVL53L8 > TXS0108E_8bitLevelShifter.fprj\n```\n\n## Export Files\n\nAvailable in the Fusion 360 Output folder on Google Drive:\n\n- `TXS0108E_8bitLevelShifter v23.brd` — EAGLE board file\n- `TXS0108E_8bitLevelShifter v14.sch` — Schematic file\n- `TXS0108E_8bitLevelShifter v23.f3d` — Fusion 360 archive (3D)\n- `TXS0108E_8bitLevelShifter v23.usdz` — 3D model for AR/Hydrogen\n- Silkscreen top/bottom PNGs\n- `board_parts.json`, `board_outline.json`, `board_netlist.json`\n",
