NCV7349D13R2G

onsemi · CAN Transceivers · SOIC-8

NCV7349D13R2G from onsemi, 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 Transmit data input; a low input drives the bus dominant, it has internal pull-up current, VIH is 2.0 V to VIO and VIL is −0.3 V to +0.8 V.
2 GND power_in Ground reference; all voltages in the datasheet are referenced to this pin.
3 VCC power_in Supply voltage, 4.75 V to 5.25 V in the recommended operating range; undervoltage detection on VCC is 2 V to 4 V.
4 RxD output Receive data output that goes low when the bus is dominant, with IOL of 1.6 mA to 12 mA at VRxD = 0.4 V.
5 VIO power_in Supply for the digital inputs and outputs (TxD, RxD, STB) on the NCV7349-3, specified at 2.8 V to 5.5 V and to be connected to the microcontroller supply; pin 5 is not connected on the NCV7349-0.
6 CANL bidirectional Low-level CAN bus line, low in dominant mode, with dominant output voltage of 0.5 V to 1.75 V.
7 CANH bidirectional High-level CAN bus line, high in dominant mode, with dominant output voltage of 3.0 V to 4.25 V.
8 STB input Standby mode control input with internal pull-up current; VIH is 2.0 V in standby mode and VIL is −0.3 V to +0.8 V in normal mode.
