Recommended Operating Conditions Parameter Symbol Test Condition Min Typ Max Unit Ambient Operating Temperature* TA 150 Mbps, 15 pF, 5 V –40 25 125* °C Supply Voltage VDD1 2.5 — 5.5 V VDD2 2.5 — 5.5 V *Note: The maximum ambient temperature is dependent on data frequency, output loading, number of operating channels, and supply voltage. Table 2.

The nominal output impedance of an isolator driver channel is approximately 50 , ±40%, which is a combination of the value of the on-chip series termination resistor and channel resistance of the output driver FET. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces. 2. tPSK(P-P) is the magnitude of the difference in propagation delay times measured between different units operating at the same supply voltages, load, and ambient temperature. 3. Start-up time is the time period from the application of power to valid data at the output. |
