The 3.3-V supplied SN65HVD23x family of CAN transceivers are electrically interchangeable with 5-V CAN
transceivers. The differential output is the same. The recessive common-mode output is the same. The dominant
common-mode output voltage is a couple hundred millivolts lower than 5-V supplied drivers, while the receivers
exhibit identical specifications as 5-V devices.
Electrical interoperability does not assure interchangeability however. Most implementers of CAN buses
recognize that ISO 11898 does not sufficiently specify the electrical layer and that strict standard compliance
alone does not ensure interchangeability. This comes only with thorough equipment testing.
