A bidirectional signal conditioning chip for a USB Type-C cable and a USB Type-C cable are provided. The chip includes a memory, a processor and a transfer driver. The transfer driver is configured to regenerate and transmit a high speed signal; the memory is configured to store a program code; the processor is configured to call the program code, and perform the following operations when the program code is executed: determining a data transmission direction and a type supported by transmitted data of the USB Type-C cable; configuring on-off states of buffers in the transfer driver based on the data transmission direction and the supported type, so that a data output direction of the transfer driver is consistent with the data transmission direction.
