MCP2558FD-H

Microchip Tech · CAN Transceivers · SOIC-8

MCP2558FD-H from Microchip Tech, 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 that drives CANH/CANL dominant when Low and recessive when High, with an internal pull-up of nominal 33 kΩ to VIO on the MCP2558FD.
2 VSS power_in Ground supply pin.
3 VDD power_in Positive supply voltage pin that supplies the transmitter and receiver.
4 RXD output CMOS-compatible receive data output that is High when the bus is recessive and Low when dominant, driven to VIO on the MCP2558FD.
5 VIO power_in Digital I/O supply pin for TXD, RXD and S, which provides the internal level shifter on the MCP2558FD.
6 CANL bidirectional CAN low-level voltage I/O that drives the low side of the CAN differential bus and disconnects from the bus when the device is unpowered.
7 CANH bidirectional CAN high-level voltage I/O that drives the high side of the CAN differential bus and disconnects from the bus when the device is unpowered.
8 S input Silent mode input that sets Normal or Silent mode, where in Silent mode the transmitter is off and the high-speed receiver stays active, with an internal MOS pull-up to VIO (typically 660 kΩ at 5 V, 1.1 MΩ at 3.3 V, 4.4 MΩ at 1.8 V).
