Overview
The CRT8002-018HR is a CRT video attributes controller manufactured by SMSC. It functions as a parity generator within the logic circuit category. The device is housed in a DIP package with 28 terminals arranged in a dual inline configuration. It utilizes MOS technology and is designed for commercial temperature operation ranges.
Feature Summary
- Integrates CRT video attributes control capabilities
- Includes built-in parity generation functionality
- Utilizes MOS semiconductor technology
Applications
- CRT video display systems
- Video attribute control circuits
- Parity checking applications
Procurement Notes
Verify the specific suffix -018HR against official SMSC documentation to confirm pinout and electrical specifications. Ensure compatibility with existing CRT video architectures. Confirm lead-free status if required, as historical data indicates non-Rohs compliance for similar variants. Request current datasheets from authorized distributors to validate availability and exact technical parameters before integration.
Selection Notes
Select this component when designing legacy CRT video interfaces requiring integrated attribute control and parity generation. Compare performance requirements against newer video controllers if modernizing systems. Verify that the 28-pin DIP form factor fits the target PCB layout constraints. Ensure the MOS technology meets the power and speed requirements of the specific video application.
Part Context
This part belongs to the CRT8002 series of video controllers produced by SMSC. These components were widely used in computer graphics systems for managing CRT display parameters. The series includes various speed grades and package options, serving as specialized logic chips for video signal processing and synchronization tasks in older computing hardware.
Replacement Considerations
Direct substitutes include other CRT8002 variants such as CRT8002B-033 or CRT8002-018HR equivalents from compatible manufacturers. Verify functional equivalence regarding video attribute control and parity generation. Check pin-to-pin compatibility to ensure seamless replacement without PCB redesign.
