THVD1450DGKR from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receive data output, logic high when differential bus voltage exceeds positive input threshold VTH+. |
| 2 | RE | input | Receiver enable input (active low) with internal 2-MΩ pull-up resistor to VCC. |
| 3 | DE | input | Driver enable input (active high) with internal 2-MΩ pull-down resistor to ground. |
| 4 | D | input | Driver data input; when DE = high, controls differential output state (high → A high/B low, low → A low/B high). |
| 5 | GND | power_in | Device ground and receiver common-mode voltage reference. |
| 6 | A | bidirectional | Differential bus terminal A, bidirectional with ±15 V input range and ±30 kV HBM ESD protection. |
| 7 | B | bidirectional | Differential bus terminal B (complementary to A), bidirectional with ±15 V input range and ±30 kV HBM ESD protection. |
| 8 | VCC | power_in | Power supply input for device operation, required supply range 3 V to 5.5 V. |
