Overview
The LM2451TB/NOPB is a monolithic triple-channel driver designed for CRT and DTV applications. It operates with a supply voltage range of 20V to 220V and features a bandwidth of 12 MHz. The device provides DC-coupled outputs capable of driving high-voltage loads directly. It integrates protection mechanisms including thermal shutdown and short-circuit protection to ensure reliable operation in demanding display environments.
Feature Summary
- Triple-channel architecture for simultaneous signal processing
- High-voltage compatibility up to 220V
- DC-coupled output configuration
- Integrated thermal and short-circuit protection
Applications
- CRT television drivers
- Direct View Tube (DVT) systems
- Industrial display controllers
Procurement Notes
Verify the exact suffix against the manufacturer's current datasheet, as legacy part numbers may have specific ordering constraints or environmental compliance variations. Confirm package availability and lead times through authorized distributors. Ensure the component matches the required RoHS status and operating temperature range for your specific design implementation.
Selection Notes
Select this component when a high-voltage, multi-channel driver is required for analog video signals. It is suitable for designs needing direct coupling without external level shifting. Consider the 12MHz bandwidth for signal fidelity requirements. Evaluate thermal management needs due to the high operating voltage and power dissipation characteristics inherent in CRT driver applications.
Part Context
This part belongs to the LM24xx series of triple-channel drivers from Texas Instruments, originally developed by National Semiconductor. These devices were widely used in consumer electronics for cathode ray tube displays. The NOPB suffix indicates a lead-free and environmentally friendly version compliant with RoHS standards, replacing earlier non-compliant variants in the product line.
Replacement Considerations
Compatible substitutes include the LM2450 and LM2452 from the same family, offering similar triple-channel functionality but with different bandwidth specifications. Verify pinout compatibility and electrical parameters before substitution.
