产品概览
The ISO1050DUBR from Texas Instruments is a galvanically isolated CAN transceiver meeting ISO 11898-2, with 2500 Vrms isolation in an 8-pin SOP (DUB) package. It supports CAN data rates up to 1 Mbps with 150 ns typical loop delay, 50 kV/us CMTI, and -27V to 40V bus fault protection. The R suffix denotes tape-and-reel packaging.
