SN65HVD78DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 (digital output) from the bus receiver. |
| 2 | RE | input | Active-low receiver enable digital input; the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum for this input. |
| 3 | DE | input | Active-high driver enable digital input; the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum for this input. |
| 4 | D | input | Driver data input (digital input); the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum, with absolute maximum voltage of -0.3 V to 5.7 V. |
| 5 | GND | power_in | Local device ground, the reference potential for the device. |
| 6 | A | bidirectional | Bus I/O: driver output or receiver input, complementary to B; voltage at A or B is limited to -13 V to 16.5 V per the absolute maximum ratings. |
| 7 | B | bidirectional | Bus I/O: driver output or receiver input, complementary to A; voltage at A or B is limited to -13 V to 16.5 V per the absolute maximum ratings. |
| 8 | VCC | power_in | Supply pin; the datasheet specifies 3 V to 3.6 V (3.3 V nominal), with absolute maximum of -0.5 V to 5 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
