MC1496BDR2

Overview

The MC1496BDR2 is a balanced modulator and demodulator integrated circuit manufactured by onsemi. It operates within an FM frequency range up to 300MHz. The device is housed in a 14-SOIC surface-mount package with a width of 3.90mm. It functions as an RF IC designed for applications where the output voltage represents the product of an input signal voltage and a switching carrier function. The component utilizes silicon technology and supports balanced modulation formats.

Feature Summary

• Implements balanced modulation and demodulation functionality for RF signal processing
• Designed to generate output voltage proportional to the product of input signal and carrier switching functions
• Supports FM application frequencies up to 300MHz

Applications

• RF modulation circuits
• Demodulator stages in communication systems
• Signal processing where output is a product of signal and carrier

Procurement Notes

Verify component status carefully as this part number is officially listed as obsolete and no longer manufactured by onsemi. Sourcing should focus on available substitute part numbers such as MC1496BDR2G which offers direct replacement compatibility. Confirm RoHS compliance requirements against the specific variant, as the original MC1496BDR2 is noted as non-compliant while the G-suffixed version adheres to environmental standards. Ensure the 14-SOIC package dimensions match the target PCB footprint.

Selection Notes

Select this component for designs requiring a dedicated balanced modulator/demodulator IC operating at frequencies up to 300MHz. The 14-SOIC package is suitable for surface-mount assembly. Consider the MC1496BDR2G variant if current manufacturing availability and RoHS compliance are mandatory project requirements. Verify that the 5mA supply current and 12V maximum voltage ratings align with the system power budget and thermal constraints.

Part Context

The MC1496BDR2 belongs to the MC1496 series of balanced modulators and demodulators produced by onsemi. This series is engineered for RF applications requiring precise multiplication of signal and carrier voltages. The device is distinct from general-purpose mixers by its specific balanced architecture optimized for FM modulation tasks. It represents a legacy silicon-based solution within onsemi's analog signal processing portfolio.

Replacement Considerations

The MC1496BDR2G is identified as a direct substitute part number. It maintains functional equivalence while addressing the obsolescence of the original MC1496BDR2. The G-suffixed variant typically indicates RoHS compliance, differing from the non-compliant status of the base model. Designers should verify pinout compatibility and electrical specifications remain identical before transitioning.
