Its physical layer compliance covers ISO 11898-2:2016 and ISO 11898-5:2007, with supported data rates up to 8 Mbps. The interface uses a VIO terminal for IO level shifting across 1.8 V, 2.5 V, 3.3 V, and 5 V logic systems, with a VIO supply range of 1.7 V to 5.5 V.
The device is offered in a DDF package, 8-pin SOT, with a 2.90 mm x 1.60 mm body. Electrical limits include -58 V to 58 V absolute maximum voltage on CANH and CANL, -45 V to 45 V maximum differential bus voltage, and +/-58 V CAN bus fault protection. Receiver specifications include +/-12 V common-mode input capability, 500 mV to 900 mV normal-mode threshold voltage, and 100 mV receiver hysteresis.
