MC1496DG

Overview

The MC1496DG is a balanced modulator and demodulator integrated circuit manufactured by onsemi. Designed for applications where the output voltage represents the product of an input signal voltage and a switching carrier function, this component operates within a frequency range of 80 MHz to 300 MHz. It requires a maximum supply current of 5 mA and supports a maximum supply voltage of 12 V. The device functions reliably across an operating temperature range from 0°C to +70°C. It is housed in a 14-pin SOIC surface-mount package with dimensions of 8.75 mm length, 4 mm width, and 1.5 mm height.

Feature Summary

• Performs balanced modulation and demodulation by generating an output proportional to the product of signal and carrier inputs
• Operates at radio frequencies up to 300 MHz using silicon technology
• Utilizes a compact 14-lead Small Outline Integrated Circuit (SOIC) surface-mount package

Applications

• FM modulation circuits
• RF communication systems requiring balanced mixing
• Signal processing applications involving carrier switching functions

Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's official documentation to confirm package type and availability status. Cross-reference the datasheet revision date to ensure compliance with current environmental standards such as RoHS. Confirm that the 14-SOIC footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a dedicated balanced modulator is required for frequencies between 80 MHz and 300 MHz. Ensure the application environment remains within the specified 0°C to +70°C operational temperature range. Verify that the system power supply does not exceed the 12 V maximum rating and that the current consumption fits within the 5 mA limit.

Part Context

This part belongs to the MC1496 series of balanced modulators and demodulators. It shares functional similarities with other variants like the MC1496DR2G but differs in packaging and potentially manufacturing lot specifications. The MC1496DG specifically utilizes the SOIC-14 package format, distinguishing it from tape-and-reel or tube-only distribution variants found in the same family.

Replacement Considerations

Public records indicate the MC1496DG has reached End-of-Life (EOL) status. Designers should consult the manufacturer's Product Change Notification (PCN) for approved substitute components or alternative package options.
