MC44BC374CDTBR2

Video Processing Overview

The MC44BC374CDTBR2 is a high-integration video modulator IC manufactured by Motorola. It supports PLL-tuned operation for both UHF and VHF frequency bands, enabling audio and video signal modulation within consumer circuit applications. The device utilizes a BICMOS process technology and operates with a supply voltage range of 4.5V to 5.5V. Communication and configuration are managed via an I2C control interface. The component is housed in a 16-pin TSSOP package, designated as PDSO16 in some documentation.

Video Processing Feature Summary

• Integrates PLL-tuned modulation capabilities for combined UHF and VHF band support
• Utilizes I2C serial interface for digital control and configuration
• Employs BICMOS technology for high integration in consumer circuits

Video Processing Applications

• Consumer video equipment requiring integrated modulation
• UHF and VHF broadcast signal generation systems
• Audio/video processing modules in home entertainment devices

Video Processing Procurement Notes

Verify the RoHS status carefully, as sources indicate this specific part number may be non-compliant. Confirm the manufacturer origin, noting that Freescale documentation exists for the base model MC44BC374, while Motorola branding appears on distributor listings. Ensure the 16-TSSOP package matches your PCB footprint requirements before procurement.

Video Processing Selection Notes

Select this component when a single-chip solution for both VHF and UHF modulation is required in consumer electronics. The I2C interface simplifies system design compared to parallel control schemes. Verify compatibility with the 4.5V to 5.5V power supply rails typical of such consumer circuits. Consider the BICMOS process implications for noise performance in sensitive audio/video paths.

Video Processing Part Context

This part belongs to the MC44BC374 family of high-integration modulators. The suffix 'CDTBR2' typically denotes specific packaging (TSSOP) and tape-and-reel delivery options. While originally associated with Motorola, later datasheets reference Freescale Semiconductor, reflecting corporate acquisitions. The base model serves as a standard for integrated audio/video modulation in legacy consumer hardware designs.

Video Processing Replacement Considerations

Direct substitutes are not explicitly confirmed in public data. The base model MC44BC374 shares core functionality but may differ in packaging or revision. Cross-reference with other high-integration PLL modulators from the same manufacturer family if pin compatibility is critical.
