Overview
The LM2467TA is a monolithic triple CRT driver manufactured by National Semiconductor. It integrates three high input impedance, wide bandwidth video amplifiers designed for color monitor applications. The device features a 7.5 ns response time and includes on-chip ROM, 512-character RAM, and four digital-to-analog converters (DACs). It operates within an ambient temperature range of -40°C to 115°C and is housed in a 9-pin TO-220 package.
Feature Summary
- Integrates three high input impedance video amplifiers with wide bandwidth for CRT drive applications
- Includes embedded memory components consisting of ROM and 512-character RAM alongside four DACs
- Designed specifically for use in color monitor systems requiring high-speed signal processing
Applications
- Color monitor circuit design
- CRT display driver systems
- Video signal amplification modules
Procurement Notes
Verify the manufacturer designation as National Semiconductor or Texas Instruments when sourcing this component. Confirm the package type is 9-pin TO-220 and ensure the operational temperature range meets specific environmental requirements. Cross-reference datasheets to confirm the presence of integrated ROM, RAM, and DACs, as these are critical functional elements distinct from standard amplifier ICs.
Selection Notes
Select the LM2467TA for applications requiring integrated CRT driving capabilities with embedded memory and DAC functions. Ensure compatibility with color monitor architectures that utilize triple-channel video amplification. Verify thermal management solutions suitable for the TO-220 package given the specified operating temperature range.
Part Context
This component belongs to the LM24 series of CRT drivers produced by National Semiconductor. Similar parts in the series include the LM2469TA, which offers comparable functionality with a 9 ns response time. These devices were commonly used in legacy video display equipment before the widespread adoption of flat-panel technologies.
Replacement Considerations
The LM2469TA is a documented substitute within the same product family, offering similar triple-channel architecture with a 9 ns response time. Verify pinout compatibility and electrical specifications before substitution.
