ISL71026MEVAL1Z 2. Functional Description 2.3.1 D Pin The D pin is the digital input to the driver of the transceiver. A digital bit pattern is applied at this pin. A logic 1 on the D pin puts the CANH and CANL differential pins in the recessive state. A logic 0 on the D pin, puts the CANH and CANL differential pins in the dominant state. - Page 6 ISL71026MEVAL1Z 2.
