SN65HVD12DR from Texas Instruments, in a SOP-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 output reflecting the state of the RS-485 differential bus (A-B). Sourced up to |
| 2 | RE | input | Active-low receiver enable. Drive low to enable receiver output R; drive high to place R in high-impedance (used to enter low-power standby together with DE=0). |
| 3 | DE | input | Active-high driver enable. Drive high to enable the differential driver onto A/B; drive low to place A/B in high-impedance. |
| 4 | D | input | Driver data input. CMOS logic input whose state is transmitted differentially on A/B when DE is high. VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 5 | GND | power_in | Local device ground / reference potential. |
| 6 | A | bidirectional | RS-485 differential bus I/O, non-inverting side. Driver output or receiver input, complementary to B. Rated -7 V to 12 V continuous, ±16-kV HBM ESD. |
| 7 | B | bidirectional | RS-485 differential bus I/O, inverting side. Driver output or receiver input, complementary to A. Rated -7 V to 12 V continuous, ±16-kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage, 3 V to 3.6 V nominal. ICC ≈ 9 mA active, ≈ 1 μA standby (RE high, DE low). |
