Fault-tolerant CAN transceiver
Product specification
TJA1054A
PINNING
SYMBOL PIN
DESCRIPTION
INH
1 inhibit output for switching an external voltage regulator if a wake-up signal occurs
TXD
2 transmit data input for activating the driver to the bus lines
RXD
3 receive data output for reading out the data from the bus lines
ERR
4 error, wake-up and power-on indication output; active LOW in normal operating mode when the bus
has a failure, and in low power modes (wake-up signal or in power-on standby)
STB
5 standby digital control signal input (active LOW); together with the input signal on pin EN this input
determines the state of the transceiver (in normal and low power modes); see Table 2 and Fig.3
EN
6 enable digital control signal input; together with the input signal on pin STB this input determines
the state of the transceiver (in normal and low power modes); see Table 2 and Fig.3
WAKE
7 local wake-up signal input (active LOW); both falling and rising edges are detected
RTH
8 termination resistor connection; in case of a CANH bus wire error the line is terminated with a
predefined impedance
RTL
9 termination resistor connection; in case of a CANL bus wire the line is terminated with a predefined
impedance
