THVD1452DGSR from Texas Instruments, in a VSSOP-10-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receive data output providing logic-level representation of RS-485 bus data received by the receiver circuit |
| 2 | RE | input | Receiver enable input, active low with 2-MΩ internal pull-up, controls receiver circuit monitoring of RS-485 bus |
| 3 | DE | input | Driver enable input, active high with 2-MΩ internal pull-down, controls driver circuit transmission on RS-485 bus |
| 4 | D | input | Driver data input accepting digital logic data for transmission on RS-485 bus when driver is enabled |
| 5 | GND | power_in | Device ground providing 0V reference and power return path for all device circuits |
| 6 | Y | output | Digital bus output Y complementary to Z, provides full-duplex differential signaling on RS-485 transmit line Y |
| 7 | Z | output | Digital bus output Z complementary to Y, provides full-duplex differential signaling on RS-485 transmit line Z |
| 8 | B | input | Bus input B complementary to A, connects to RS-485 differential bus line B for receiver monitoring |
| 9 | A | input | Bus input A complementary to B, connects to RS-485 differential bus line A for receiver monitoring |
| 10 | VCC | power_in | Power supply input requiring 3.3-V to 5-V supply voltage for device operation |
