SN75HVD07DR from Texas Instruments, in a SOIC-8. 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 | Receiver output, which is enabled by the active-low receiver enable RE as stated in the datasheet's receiver enable description. |
| 2 | RE | input | Active-low receiver enable; the datasheet states that DE and RE can be externally connected together to function as direction control. |
| 3 | DE | input | Active-high driver enable; the datasheet states that DE and RE can be externally connected together to function as direction control. |
| 4 | D | input | Driver data input that drives the differential I/O bus port (A and B) when the driver is enabled. |
| 5 | GND | power_in | Ground reference pin for the device. |
| 6 | A | bidirectional | Bus pin of the differential I/O bus port, where the driver outputs and receiver inputs connect internally; the datasheet states the port offers minimum loading to the bus when the driver is disabled or not powered. |
| 7 | B | bidirectional | Bus pin of the differential I/O bus port, where the driver outputs and receiver inputs connect internally; the datasheet states the port offers minimum loading to the bus when the driver is disabled or not powered. |
| 8 | VCC | power_in | Positive supply pin for the device; the supply voltage limits are given in the Absolute Maximum Ratings and Recommended Operating Conditions, which are not in the pages provided. |
