LOW level. The microcontroller should react to this condition by switching the transceiver

back to normal operation (via pin 8). Because the receiver is slow in Standby mode, the

first message will be lost.

[1] In accordance with “IEC 60747-1”. An alternative definition of virtual junction temperature is:

Tvj = Tamb + Pd  Rth(vj-a), where Rth(j-a) is a fixed value to be used for the calculation of Tvj. The rating for Tvj

limits the allowable combinations of power dissipation (Pd) and ambient temperature (Tamb).
