Renesas Electronics M59330P
The M59330P is an integrated circuit for two-line LAN transceivers, conforming to J1850 specifications. The chip incorporates bus line anomaly detection functions; anomalous behavior causes the ERR signal to go to "L". By setting the standby signal to "L", a low consumption current state is maintained.DESCRIPTION
A selector causes a normal bus signal to be output to RX. At this time, the drivers BUS (+) and BUS (–) are both turned off. In standby mode, on input of "H" level to the ERR pin, error output reset occurs.FEATURES
● Conforms to SAE J1850 specifications● Internal bus line anomaly detection function
