NOTES:
5. In the operating voltage range from 6V to 8.5V the BUS OUT, V
BOH
is limited by the low power supply. In the operating voltage range
from 16V to 24V the maximum bus load is limited by the package power dissipation ratings.
6. Over-temperature shutdown with hysteresis is incorporated to protect the IC under system failure conditions.
7. Measured Current into the TX terminal is determined by Pull-Down Current Sink.
8. Propagation Delay limits are measured at the 3.875V level on BUS OUT. Rise and Fall Times are measured between 1.5V and 6.25V on
the BUS OUT terminal.
9. Measured Current into the LB EN terminal is determined by Pull-Down Current Sink.
10. The I
RX
Output Current test parameter defines Short Circuit protection limits.
11. Loss of Ground refers to loss of module (node) Ground which results in a voltage between the Battery and IC Ground of less than 0.8V.
For voltage between Battery and Ground above 0.8V, the Transceiver Bus Output may become active. The module circuit in Figure 3 is
used to measure the Loss of Ground leakage.
12. Unless otherwise noted, all Electrical Specification test conditions are as shown in Figure 4.
13. The lower limit is 6.6V or V
BATT
- 1.7V, whichever is less.
