SN65HVD37DR 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. |
| 2 | R | output | Receiver output; outputs the logic level corresponding to the bus differential input per the receiver function table, VOH ≥ 2.4V at IOH=-8mA and VOL 0.2-0.4V at IOL=8mA, goes high-impedance when RE is high or open. |
| 3 | RE | input | Receiver enable, active low; a low level enables the R output, a high level or open (default) forces R to a high-impedance state; 5V-tolerant logic input, VIH ≥2V, VIL ≤0.8V. |
| 4 | DE | input | Driver enable, active high; a high level enables the Y/Z differential driver outputs, a low level or open (default) disables the driver to high impedance; 5V-tolerant logic input, VIH ≥2V, VIL ≤0.8V. |
| 5 | D | input | Driver data input; a high level drives Y high and Z low, a low level drives Y low and Z high (open input defaults to driving Y high/Z low when DE is high); 5V-tolerant logic input, VIH ≥2V, VIL ≤0.8V. |
| 6 | GND | power_in | Ground reference; datasheet notes that both pins 6 and 7 should be connected to ground. |
| 7 | GND | power_in | Ground reference; datasheet notes that both pins 6 and 7 should be connected to ground. |
| 8 | NC | unconnected | No internal connection. |
| 9 | Y | output | Noninverting differential driver output; |
| 10 | Z | output | Inverting differential driver output, complementary to Y; |
| 11 | B | input | Inverting receiver differential input; bus input voltage range -7V to 12V (separately or common mode), differential input voltage range -12V to 12V, part of the RS-485 bus port. |
| 12 | A | input | Noninverting receiver differential input; bus input voltage range -7V to 12V (separately or common mode), differential input voltage range -12V to 12V, part of the RS-485 bus port. |
| 13 | VCC | power_in | Supply voltage input, 3V to 3.6V (3.3V nominal); datasheet notes that both pins 13 and 14 should be connected to the supply voltage. |
| 14 | VCC | power_in | Supply voltage input, 3V to 3.6V (3.3V nominal); datasheet notes that both pins 13 and 14 should be connected to the supply voltage. |
