74HC280N,652

Overview

The 74HC280N,652 is a 9-bit parity generator and checker manufactured by NXP USA Inc. It operates within a supply voltage range of 2 V to 6 V and is housed in a 14-pin DIP package. The device functions as both a parity generator for odd or even data streams and a checker for error detection. It supports through-hole mounting and is designed for standard logic applications requiring reliable parity calculation capabilities.

Feature Summary

• Performs 9-bit parity generation and checking operations
• Supports both odd and even parity configurations
• Compatible with standard HC logic families

Applications

• Data communication systems for error detection
• Memory modules requiring parity verification
• Microcontroller peripheral interfaces

Procurement Notes

Verify the specific suffix '652' against official NXP documentation to confirm tape-and-reel or tube packaging details. Ensure the operating voltage requirements align with your system design, as the device supports a wide range from 2 V to 6 V. Cross-reference the pinout diagram with your PCB layout to guarantee correct signal routing for the nine data inputs and outputs.

Selection Notes

Select this component when a dedicated hardware solution for 9-bit parity is required without software overhead. It is suitable for designs needing robust error detection in data transmission paths. Consider the DIP-14 package if prototyping or through-hole assembly is preferred over surface-mount alternatives. Verify compatibility with your existing logic family voltage levels before integration.

Part Context

This part belongs to the NXP 74HC series of high-cmos logic devices. The 74HC280 specifically addresses parity generation and checking needs. It complements other logic components by providing a standardized method for data integrity verification in digital circuits, ensuring reliable operation across various industrial and consumer electronic applications.

Replacement Considerations

Check for direct equivalents such as the SN74HC280 from Texas Instruments or similar variants from other manufacturers. Ensure that any substitute maintains the same 9-bit functionality and 14-pin DIP footprint. Verify electrical characteristics like supply voltage ranges and propagation delays to ensure seamless integration into existing designs.
