B1 |
TXD |
Transmit Data Input. Drive TXD high to set the driver in the recessive state. Drive TXD low to set the driver in the dominant state. TXD has an internal pullup to VDD.
|
| 2 |
B2 |
GND |
Ground. |
| 3 |
B3 |
VDD |
Supply Voltage. Bypass VDD to GND with a 0.1µF capacitor. |
| 4 |
B4 |
RXD |
Receive Data Output. RXD is high when CANH and CANL are in the recessive state. RXD is low when CANH and CANL are in the dominant state. |
| 5 |
A4 |
SHDN |
Shutdown Input, CMOS/TTL compatible. Drive SHDN high to put MAX33040E/MAX33041E in shutdown. SHDN has an internal pulldown resistor to GND. |
| 6 |
A3 |
CANL |
CAN Bus-Line Low
|
| 7 |
A2 |
CANH |
CAN Bus-Line High
|
| 8 |
A1 |
STBY |
Standby Mode. A logic-high on STBY pin selects the standby mode. In standby mode, the transceiver is not able to transmit data and the receiver is in low power mode. A logic-low on STBY pin puts the transceiver in normal operating mode. A 39.2kΩ external resistor can be used to connect the STBY pin to ground for slow slew rate. |
