LM2426TE

Overview

The LM2426TE is a monolithic triple channel 30 MHz DTV driver manufactured by National Semiconductor. It is an integrated high voltage CRT driver circuit designed for use in HDTV applications. The IC contains three high input impedance, high output current drivers suitable for driving CRT deflection coils or similar loads in digital television sets.

Feature Summary

• Monolithic integration of three high-voltage driver channels
• Designed specifically for high-definition television (HDTV) applications
• Features high input impedance and high output current capabilities

Applications

• High-definition television (HDTV) sets
• CRT driver circuits for digital video displays
• Deflection coil driving in consumer electronics

Procurement Notes

Verify the manufacturer origin as National Semiconductor, now part of Texas Instruments. Confirm the package type is TO-220-11 with formed leads. Ensure the datasheet matches the specific 30 MHz DTV driver description to avoid confusion with other video amplifiers.

Selection Notes

Select this component when a dedicated triple-channel high-voltage driver is required for CRT-based HDTV designs. Consider the TO-220-11 package for thermal management and board space constraints. Verify compatibility with the specific deflection requirements of the target display system.

Part Context

This part belongs to the LM2426 family of video amplifiers and CRT drivers. It is distinct from standard operational amplifiers due to its high voltage handling and specific integration for television deflection systems. The TE suffix typically denotes a specific tape and reel or packaging variant within the National Semiconductor lineup.

Replacement Considerations

Check for LM2426TE/NOPB as a potential lead-free equivalent. Verify pinout and electrical specifications against any cross-referenced parts from Texas Instruments or other manufacturers before substitution.
