HGA1042M-3

HGSEMI · CAN Transceivers · SOP-8

HGA1042M-3 from HGSEMI, in a SOP-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 Transmit data input; when left floating an internal pull-up keeps the transceiver in the recessive bus state, and the dominant timeout releases the bus if TXD is held low longer than tdom_TXD (0.3 to 5 ms).
2 GND power_in Ground reference for the device.
3 VCC power_in Main supply input, rated 4.5 to 5.5 V in normal operation, with undervoltage protection that tri-states the bus outputs below the threshold (3.5 to 4.5 V).
4 RXD output Receive data output; it reads high in recessive bus or standby without wake request and goes low when the bus is dominant or a wake-up request is detected, and it floats when VCC is removed.
5 VIO/SPLIT power_in I/O level-shifting supply input (2.8 to 5.5 V operating range, supports 3.3 V MCUs on HGA1042-3) that doubles as the SPLIT common-mode regulated output at 0.5VCC in normal mode, which should be tied to the midpoint of the termination; it floats in standby mode.
6 CANL bidirectional Low-level CAN bus line, which is part of the differential bus driven and received by the transceiver and tolerates a bus common-mode range of -70 to 70 V.
7 CANH bidirectional High-level CAN bus line, which is part of the differential bus driven and received by the transceiver and tolerates a bus common-mode range of -70 to 70 V.
8 STB input Standby mode control input; driving it low selects normal mode, while high or floating selects standby mode, and an internal pull-up keeps the transceiver in standby when the pin is left open.
