The maximum operating temperature range for the UCC27424QDRQ1 is -40°C to 150°C.
To ensure proper biasing, connect the input pins (VIN and VCC) to a stable voltage source, and ensure the output pins (OUTA and OUTB) are properly terminated with a load impedance.
For optimal performance, use a 4-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a decoupling capacitor (e.g., 10nF) between VIN and GND.
Use ESD protection devices (e.g., TVS diodes) on the input and output pins, and ensure the PCB design includes ESD protection features, such as a ground plane and ESD-sensitive component placement.
Power up the device in the following sequence: VIN, VCC, and then the output loads. Power down in the reverse sequence.
