THVD1410DR 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; provides logic high when receiver is enabled and differential input voltage exceeds positive threshold VTH+, and logic low when voltage is below VTH-. |
| 2 | RE | input | Receiver enable input, active low with internal 2-MΩ pull-up resistor; receiver is enabled when RE is low and disabled with high-impedance output when RE is high or left open. |
| 3 | DE | input | Driver enable input, active high with internal 2-MΩ pull-down resistor; when DE is high, outputs A and B follow data input D; when DE is low, outputs turn high-impedance. |
| 4 | D | input | Driver data input; logic high at D causes A to go high and B to go low; logic low reverses the output states. |
| 5 | GND | power_in | Device ground reference connection. |
| 6 | A | bidirectional | Differential bus I/O port A, complementary to B; driven by D when driver is enabled via DE, receives differential data when receiver is enabled via RE. |
| 7 | B | bidirectional | Differential bus I/O port B, complementary to A; driven inverse to A by D when driver is enabled via DE, receives differential data when receiver is enabled via RE. |
| 8 | VCC | power_in | Power supply voltage input with operating range of 3.3 V to 5.5 V and typical supply current less than 3 mA during operation. |
