LM2419T

Overview

The LM2419T is a monolithic triple CRT driver manufactured by National Semiconductor. It integrates three high-speed output stages designed for cathode ray tube applications, providing the necessary drive current and voltage swing to control electron beams. The device features fast switching characteristics suitable for high-frequency video signals.

Feature Summary

• Integrates three independent high-speed output drivers on a single chip
• Designed specifically for driving CRT deflection and beam modulation circuits
• Provides robust output capability for analog video signal processing

Applications

• Color CRT display systems
• Video monitor circuitry
• Industrial imaging equipment with CRT interfaces

Procurement Notes

Verify the manufacturer source carefully as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'T' matches the required tape-and-reel packaging variant if applicable. Ensure the datasheet version corresponds to the original National Semiconductor publication rather than generic TI equivalents.

Selection Notes

Select this component when designing legacy CRT-based displays requiring integrated triple-channel drive. Compare propagation delay and output current specifications against alternative monolithic CRT drivers. Ensure the supply voltage range aligns with the system's power rails and thermal management supports the package type.

Part Context

This part belongs to the LM24 series of monolithic triple CRT drivers produced by National Semiconductor. These components were standard solutions for color television and monitor designs before the widespread adoption of flat-panel displays. The series includes variants with different speed grades and package options.

Replacement Considerations

Check for direct pin-compatible replacements within the LM24 family or equivalent triple CRT drivers from other manufacturers. Verify that any substitute maintains the same electrical characteristics and package footprint.
