SN65HVD33DR from Texas Instruments, in a SOIC-14. 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 | NC | unconnected | No internal connection; must be left floating. |
| 2 | R | tri_state | Receive data output; high impedance when receiver is disabled (RE high or open). |
| 3 | RE | input | Receiver enable input (active low); receiver output R is enabled when RE is low. |
| 4 | DE | input | Driver enable input (active high); driver outputs Y and Z are enabled when DE is high. |
| 5 | D | input | Driver data input; output state of Y and Z follows D when driver is enabled. |
| 6 | GND | power_in | Local device ground reference potential. |
| 7 | GND | power_in | Local device ground reference potential (internally connected to pin 6). |
| 8 | NC | unconnected | No internal connection; must be left floating. |
| 9 | Y | tri_state | Driver output Y; complementary differential output to Z; high impedance when driver is disabled. |
| 10 | Z | tri_state | Driver output Z; complementary differential output to Y; high impedance when driver is disabled. |
| 11 | B | input | Receiver differential bus input B; complementary input pair with A for RS-485 reception. |
| 12 | A | input | Receiver differential bus input A; complementary input pair with B for RS-485 reception. |
| 13 | VCC | power_in | 3.3-V supply voltage (3.0 V to 3.6 V operating range per Section 7.3 Recommended Operating Conditions). |
| 14 | VCC | power_in | 3.3-V supply voltage (internally connected to pin 13; 3.0 V to 3.6 V operating range). |
