Abstract
A transceiver suitable for interfacing a logic device to a shared bus includes a transmit node that receives an input signal from the logic device and an I/O node, that is coupled to the shared bus. The transceiver may be designed for use with a shared-bus, single master, multiple slave architecture, e.g., a Local Interconnect Network (LIN). In a LIN compliant implementation, the transceiver may be suitable for use in at least some types of automobiles and other motorized vehicles. Control logic coupled to the transmit node may assert a current driver enable signal in response to detecting an assertion of the input signal. A current driver of the transceiver is configured to draw a time varying driver current from the shared bus node after detecting an assertion of the current driver enable signal. The driver current may cause a sinusoidal transition of the shared bus voltage.
