SN65HVD74DGK 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 | VCC | power_in | Supply pin; the device operates from a 3-V to 3.6-V supply (3.3 V nominal, 5 V absolute maximum). |
| 2 | R | output | Receive data output; the recommended receiver output current is limited to -8 mA to 8 mA, and the absolute maximum is 24 mA. |
| 3 | D | input | Driver data input; logic inputs are 5-V tolerant with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 4 | GND | power_in | Reference potential; local device ground. |
| 5 | Y | output | Digital bus output Y, complementary to Z; driver output current is rated to 60 mA (recommended) and bus pins are rated -13 V to 16.5 V (absolute maximum). |
| 6 | Z | output | Digital bus output Z, complementary to Y; driver output current is rated to 60 mA (recommended) and bus pins are rated -13 V to 16.5 V (absolute maximum). |
| 7 | B | input | Digital bus input B, complementary to A; the recommended input voltage at bus pins is -7 V to 12 V (common mode). |
| 8 | A | input | Digital bus input A, complementary to B; the recommended input voltage at bus pins is -7 V to 12 V (common mode). |
