SN65HVD888DR 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. CMOS-level digital output driven by the differential receiver comparing bus pins A and B. |
| 2 | RE | input | Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance. |
| 3 | DE | input | Driver enable, active high. Drive high to enable the differential bus driver onto A/B; drive low to place the driver outputs in high-impedance. |
| 4 | D | input | Driver data input. CMOS-level digital input whose state (when DE is asserted) is transmitted differentially onto bus pins A and B. |
| 5 | GND | power_in | Local device ground / reference potential. |
| 6 | A | bidirectional | RS-485 differential bus I/O pin A (complementary to B). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω. |
| 7 | B | bidirectional | RS-485 differential bus I/O pin B (complementary to A). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω. |
| 8 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V (5 V nominal). Bypass with a local decoupling capacitor to GND. |
