Texas Instruments · CAN Transceivers · SOIC-8
HVDA540QDRQ1 from Texas Instruments, in a SOIC-8. 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 | TXD | input | CAN transmit data input: low drives the dominant bus state and high the recessive state, with VIH of 0.7 × VIO minimum and VIL of 0.3 × VIO maximum. |
| 2 | GND | power_in | Ground connection for the transceiver; all voltages are referenced to this terminal. |
| 3 | VCC | power_in | Transceiver 5-V supply with a recommended operating range of 4.68 V to 5.33 V. |
| 4 | RXD | output | CAN receive data output, low in the dominant bus state and high in the recessive state; receiver output current is limited to 20 mA absolute maximum, with IOH of −2 mA and IOL of 2 mA recommended. |
| 5 | VIO | power_in | Transceiver logic-level (I/O) supply for the HVDA54x variant, adaptable from 3 V to 5.33 V; this pin is NC on the -5 versions. |
| 6 | CANL | bidirectional | Low-level CAN bus line, with bus-fault protection from −27 V to 40 V and ±12 kV HBM ESD protection. |
| 7 | CANH | bidirectional | High-level CAN bus line, with bus-fault protection from −27 V to 40 V and ±12 kV HBM ESD protection. |
| 8 | STB/S | input | On the HVDA540 this pin is STB, the active-high standby mode select; this variant has no wake-up function. |
