SN65HVD1787DR 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 | Receive data output (VOH 2.4 V min, VOL 0.2-0.5 V) with high-impedance state when receiver disabled (RE high) |
| 2 | RE | input | Receiver enable input, active low (VIL ≤ 0.8 V); receiver disabled by default when open circuit |
| 3 | DE | input | Driver enable input, active high (VIH ≥ 2 V); driver disabled by default when open circuit |
| 4 | D | input | Driver data input (VIH ≥ 2 V); high state drives A low and B high onto differential bus when DE = high |
| 5 | GND | power_in | Local device ground, reference potential for all voltage measurements |
| 6 | A | bidirectional | Differential bus I/O complementary to B, rated -70 V to 30 V absolute maximum with ±30 V fault protection and ±16 kV HBM ESD |
| 7 | B | bidirectional | Differential bus I/O complementary to A, rated -70 V to 30 V absolute maximum with ±30 V fault protection and ±16 kV HBM ESD |
| 8 | VCC | power_in | Positive supply voltage, 4.5 V to 5.5 V range for half-duplex RS-485 transceiver operation |
