LAN TRANSCEIVER
M54617P
MITSUBISHI <CONTROL / DRIVER IC>
DESCRIPTION
The M54617P is an integrated circuit for two-wire system LAN
transceivers in compliance with J1850.
It has a built-in function detecting bus-line abnormality, and allows
ERR signal to turn to “L” in case of abnormality. In addition, the
selector permits the output of normal bus signal.
Turning the standby signal to “L” provides a low current dissipation
status, when both BUS(+) and BUS(-) of the driver are turned OFF.
Further, inputting “H” level to ERR pin when in the standby mode
allows error output to be reset.
FEATURES
G
Compliance with SAE J1850 standards
G
Built-in function detecting bus-line abnormality
APPLICATION
LAN transceivers in general and other communication transceivers
(The M59330P having the same function is available as a vehicle-
loaded LAN transceiver).
