6.4 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted) 
MIN NOM MAX UNIT
VCC Supply voltage 3 5.5 V
VI Input voltage at any bus terminal (separately or common mode)(1) –7 12 V
VIH High-level input voltage (D, DE, RE, TERM, SLR inputs) 2 5.5 V
VIL Low-level input voltage (D, DE, RE, TERM, SLR inputs) 0 0.8 V
IO Output current, driver –60 60 mA
IOR Output current, receiver –8 8 mA
RL Differential load resistance 54 60 Ω
1/tUI Signaling rate SLR = VIO 500 kbps
SLR = GND or floating 20 Mbps
TA (2) Operating ambient temperature  -40 125 °C
TJ (2) Junction temperature  -40 150 °C
(1) The algebraic convention, in which the least positive (most negative) limit is designated as minimum is used in this data sheet.
(2) Operation is specified for internal (junction) temperatures upto 150°C. Self-heating due to internal power dissipation should be considered for each application. Maximum junction temperature is internally limited by the thermal shut-down (TSD) circuit which disables the driver outputs when the junction temperature reaches typical 170°C.
