54F280DC

Overview

The MC54F280DC is a high-speed CMOS logic device belonging to the F/FAST Series, manufactured by National Semiconductor. It functions as a 9-bit parity generator and checker with complementary outputs. The component is housed in a CDIP14 ceramic dual in-line package, designed for robust performance in military-grade or high-reliability applications requiring wide temperature stability and fast switching speeds characteristic of the F-series technology.

Feature Summary

• Implements 9-bit parity generation and checking logic with complementary output signals
• Constructed using high-speed F/FAST Series CMOS technology for rapid signal processing
• Encapsulated in a hermetically sealed ceramic DIP-14 package suitable for harsh environments

Applications

• Data transmission systems requiring error detection via parity checking
• Military-grade digital logic circuits demanding high reliability
• High-speed computer memory interface circuits

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor's logic assets were acquired by Texas Instruments. Ensure the part number corresponds to the original NS fabrication or the correct TI successor designation. Confirm the ceramic DIP-14 package specification matches the required environmental sealing standards for your specific application design.

Selection Notes

Select this component when a 9-bit parity solution is required within a legacy F-series architecture. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider availability constraints due to the discontinuation of the original National Semiconductor line and potential obsolescence risks associated with older military-grade specifications.

Part Context

This device is part of the broader MC54 series of high-speed logic components originally developed by National Semiconductor. The 'F' suffix denotes the FAST series speed grade, while the 'DC' indicates the specific ceramic DIP package variant. These parts are foundational in older digital systems where deterministic timing and radiation hardness are critical operational requirements.
