LM2468TA

Overview

The LM2468TA is a monolithic triple high-gain CRT driver manufactured by National Semiconductor. It features three independent amplifier channels designed for cathode ray tube applications, providing a propagation delay of 14 nanoseconds per channel. The device integrates internal compensation to ensure stability without external components. It supports high swing output capabilities suitable for driving CRT deflection circuits directly.

Feature Summary

• Monolithic integration of three high-gain amplifier channels
• Fast 14ns propagation delay for precise timing control
• Internal frequency compensation eliminating external components
• High swing output capability for direct CRT drive

Applications

• Cathode Ray Tube (CRT) display systems
• Video signal processing circuits
• Deflection driver stages in legacy monitors

Procurement Notes

Verify the manufacturer status as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix TA indicates the required package type and temperature range. Ensure compatibility with existing CRT driver designs given the component's age. Check for availability through authorized distributors or surplus suppliers.

Selection Notes

Select this component specifically for applications requiring triple-channel CRT driving with high gain and fast response times. Consider the 14ns delay when designing timing-critical video paths. Evaluate the need for high swing outputs against the voltage requirements of the target CRT panel. Verify pinout compatibility if replacing older designs.

Part Context

The LM2468 belongs to a family of triple CRT drivers from National Semiconductor, including variants like the LM2465 and LM2469 which offer different propagation delays. These devices were standard solutions for analog video display technologies before the widespread adoption of flat-panel displays. The TA suffix typically denotes a specific industrial or commercial grade package configuration.
