MC1496M

Overview

The MC1496M is a balanced modulator and demodulator integrated circuit manufactured by Motorola. It operates within a frequency range of 80 MHz to 300 MHz and requires a supply current of 5 mA. The device is housed in a PDIP-14 package and functions across an operating temperature range of 0°C to +70°C. Power dissipation is rated at 33 mW, utilizing silicon technology.

Feature Summary

• Provides balanced modulation and demodulation capabilities for high-frequency signal processing
• Supports quadruplex multiplication allowing both input signals to vary in positive and negative voltage ranges
• Delivers high carrier suppression and low distortion through internal double differential amplifier structures

Applications

• Double sideband suppressed carrier (DSB-SC) modulation
• Amplitude modulation (AM) with appropriate DC biasing
• Synchronous detection and demodulation
• Frequency conversion and mixing applications
• Phase comparison and detection

Procurement Notes

Verify the specific manufacturer origin as the MC1496 series was originally produced by Motorola but later manufacturing rights transferred to other entities such as onsemi or NXP. Confirm that the PDIP-14 package matches the required footprint for the target design. Ensure the component meets the necessary environmental standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring precise analog multiplication or balanced modulation at frequencies up to 300 MHz. Consider the requirement for dual power supplies and external biasing networks to optimize linearity and carrier suppression. Evaluate the trade-off between the classic bipolar architecture performance and modern alternatives if space or power constraints are critical.

Part Context

The MC1496 is a classic analog multiplier IC initially developed by Motorola. It serves as a foundational component for RF communication systems requiring balanced modulation or synchronous detection. While original production has ceased, the design remains widely referenced in telecommunications and signal processing literature for its robust quadruplex multiplication capabilities.

Replacement Considerations

Public confirmed substitute part numbers include MC1496PD, MC1496DR2G, and MC1496D. Verify pin compatibility and electrical specifications against the original datasheet when transitioning between these variants.
