DESCRIPTION

The RBCAND21 series of CAN isolation transceiver module is a single channel,

high speed, industrial bus that converts TTL/CMOS level to CAN bus differential

level and uses IC integrated technology to achieve signal and power isolation.

This series consists of very compact models with a DIP8 package and a bus that

can support a maximum of 110 nodes. It features two-port isolation of 3.0kVDC,

baud rate up to 1Mbps, as well as set isolation and ESD bus protection in one.

This series is RoHS compliant and also has EN60950 safety approvals.

Size: 0.72in x 0.58in x 0.28in (18.20mm x 14.80mm x 7.10mm)
