Procurement Notes

Verify the specific suffix designation (+T&R or +C) against the target datasheet revision, as packaging and availability differ significantly between reel and tube formats. Confirm end-of-life status with the manufacturer, as this component may be subject to limited supply or discontinuation. Ensure that the 28-TSSOP footprint matches the PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing automotive displays requiring dual-channel CCFL drive with integrated dimming. Verify that the system power supply remains stable within the 4.75 V to 5.25 V window to maintain optimal controller performance. Consider the 12 mA quiescent current impact on overall system efficiency. Ensure the design accommodates the 28-TSSOP package dimensions and thermal dissipation needs for the specified 105°C maximum operating temperature.
