Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entity onsemi, given corporate acquisitions. Confirm the package type matches SOIC-14 specifications. Check RoHS compliance status against current regulatory requirements. Ensure the component meets the specified operating temperature range for your application environment. Validate pinout compatibility if replacing legacy components like RC6334.

Selection Notes

Select this component when designing systems requiring precise video signal integrity with minimal phase distortion. The low supply current makes it suitable for power-constrained portable devices. Ensure the load impedance matches the 75Ω specification for optimal performance. Verify that the minimum stable gain requirement of 1.5V/V aligns with the circuit topology. Consider the rail-to-rail swing limitations of 1.3V from either supply rail.
