CRT8002B-021P

Overview

The CRT8002B-021P is a parity generator manufactured by SMSC, now part of Microchip Technology. This component belongs to the CRT8002 series of logic integrated circuits designed for error detection in digital data transmission systems. It functions as a dedicated parity generator, calculating even or odd parity bits for input data streams. The device is intended for commercial temperature grade applications and utilizes standard dual-in-line packaging configurations typical of its era. As a discrete logic function, it supports system integrity checks without requiring complex programming.

Feature Summary

• Dedicated hardware implementation for real-time parity bit generation
• Designed for integration into digital communication and data processing architectures
• Commercial temperature rating suitable for general industrial environments

Applications

• Digital data transmission error detection systems
• Computer memory interface parity checking circuits
• Industrial control system data integrity verification

Procurement Notes

Verify manufacturer origin carefully, as SMSC assets were acquired by Microchip Technology. Confirm package type and pinout compatibility with existing PCB footprints. Check RoHS compliance status, as older SMSC parts may not meet current environmental standards. Ensure datasheet version matches the specific suffix requirements for your design.

Selection Notes

Select this component when a standalone parity generator is required rather than a combined checker/generator unit. Consider the CRT8002A series if different speed grades or package options are needed. Evaluate modern FPGA alternatives for new designs due to potential end-of-life status of legacy CMOS logic families.

Part Context

This part is part of the CRT8002 family of parity generators and checkers originally produced by Standard Microsystems Corporation (SMSC). The family includes various variants such as CRT8002B-003P and CRT8002B-021. These components were widely used in early computer systems and telecommunications equipment before being superseded by more integrated solutions.
