7.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VCC(3) Supply voltage 3 3.3 3.6 V
VI Input voltage at any bus terminal (separately or common mode)(1) –7 12 V
VIH High-level input voltage (driver, driver enable, and receiver enable inputs) 2 VCC V
VIL Low-level input voltage (driver, driver enable, and receiver enable inputs) 0 0.8 V
VID Differential input voltage –12 12 V
IO Output current, driver –60 60 mA
IO Output current, receiver –8 8 mA
RL Differential load resistance 54 60 Ω
CL Differential load capacitance 50 pF
1/tUI Signaling rate SN65HVD72 250 kbps
SN65HVD75 20 Mbps
SN65HVD78 50 Mbps
TA(2) Operating free-air temperature (See Thermal Information) –40 125 °C
TJ 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 up to 150°C. Self-heating due to internal power dissipation should be considered for each application. Maximum junction temperature is internally limited by the thermal shutdown (TSD) circuit which disables the driver outputs when the junction temperature reaches 170°C.
(3) Exposure to conditions beyond the recommended operation maximum for extended periods may affect device reliability.
