SN65HVD1780DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receiver data output. CMOS-level digital output driven by the differential receiver comparing A and B bus inputs. |
| 2 | RE | input | Receiver enable (active low). Drive low to enable the receiver output R; drive high to place R in high-impedance state. |
| 3 | DE | input | Driver enable (active high). Drive high to enable the differential driver onto the A/B bus; drive low to place driver outputs in high-impedance state. |
| 4 | D | input | Driver data input. CMOS-level digital input; logic level is transmitted differentially onto the A/B bus when DE is high. |
| 5 | GND | power_in | Local device ground reference. |
| 6 | A | bidirectional | Non-inverting RS-485 bus I/O. Driver output or receiver input (complementary to B). Fault-protected to >±70 V, ±16-kV HBM ESD. |
| 7 | B | bidirectional | Inverting RS-485 bus I/O. Driver output or receiver input (complementary to A). Fault-protected to >±70 V, ±16-kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage input. Operating range 3.15 V to 5.5 V (nominal 5 V); absolute max 7 V. |
