LM2453TA

Overview

The LM2453TA is a monolithic triple CRT driver featuring an integrated clamp and G1 blanking capability. It operates with a supply current of 35 mA and utilizes a TO-220-15 through-hole package with formed leads. Designed for display driver applications, this component provides high-speed signal processing suitable for cathode ray tube systems.

Feature Summary

• Monolithic triple channel architecture
• Integrated clamp functionality
• G1 blanking control

Applications

• CRT Driver

Procurement Notes

Verify the obsolete status of this National Semiconductor part before procurement planning. Confirm that the TO-220-15 package dimensions match your existing board layout requirements. Ensure compatibility with legacy CRT driver circuits as this component is no longer in active production by the original manufacturer.

Selection Notes

Select this component specifically for legacy CRT display designs requiring a triple driver solution. The integrated clamp and G1 blanking features reduce external component count. Verify that the 35 mA supply current fits within the system power budget and that the through-hole mounting style is supported by the assembly process.

Part Context

This component belongs to the LM24 series of monolithic triple CRT drivers manufactured by National Semiconductor, which was later acquired by Texas Instruments. The series includes variants with different propagation delays, such as the LM24 and LM2439. The LM2453TA specifically offers 6 ns performance characteristics within this family.
