LM2422TE/NOPB

Overview

The LM2422TE/NOPB is a monolithic triple CRT driver manufactured by National Semiconductor. It features a switching speed of 7.5 ns, designed for high-speed video applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports output currents up to 100mA per channel. It utilizes an 8-pin SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Triple-channel architecture for simultaneous RGB signal driving
• High-speed switching capability with 7.5 ns transition times
• Integrated protection against thermal overload and short circuits

Applications

• Color CRT display drivers
• Video monitor output stages
• Graphic adapter systems

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, noting the acquisition history. Confirm the specific suffix TE/NOPB indicates lead-free compliance and tape-and-reel packaging. Ensure the datasheet matches the 7.5 ns switching specification and 8-pin SOIC form factor to avoid confusion with other LM24 variants.

Selection Notes

Select this component when a compact triple-driver solution is required for CRT-based displays. The 7.5 ns speed suits standard resolution monitors. Compare against faster variants like the LM2412 if higher refresh rates are needed. Ensure the 5V supply rail aligns with system design constraints.

Part Context

Part of the LM24 family of monolithic CRT drivers from National Semiconductor. This series provides integrated solutions for driving electron guns in color displays, replacing discrete transistor designs. The NOPB suffix denotes non-pb (lead-free) construction compliant with environmental directives.
