AMIS4168x AMIS-41682, AMIS-41683 Fault Tolerant CAN Transceiver Description The new AMIS41682 and AMIS41683 are interfaces between the protocol controller and the physical wires of the bus lines in a control www.onsemi.com area network (CAN). AMIS41683 is identical to the AMIS41682 but has a true 3.3 V digital interface to the CAN controller. The device PIN ASSIGNMENT provides differential transmit capability but will switch in error conditions to a singlewire transmitter and/or receiver. Initially it will be used for low speed applications, up to 125 kB, in passenger cars. 1 14 INH VBAT Both AMIS41682 and AMIS41683 are implemented in I2T100 technology enabling both highvoltage analog circuitry and digital TxD 2 13 GND functionality to coexist on the same chip. These products consolidate the expertise of ON Semiconductor for RxD 3 12 CANL incar multiplex transceivers and support together with 0REMX002XTP (VAN), AMIS30660 and AMIS30663 (CAN 4 11 CANH ERR high speed) and AMIS30600 (LIN) another widely used physical layer.
