74HC280D-Q100J

Overview

The Nexperia 74HC280D-Q100J is a 9-bit odd/even parity generator and checker housed in an SO14 (SOT108-1) plastic small outline package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device provides complementary even (PE) and odd (PO) outputs, where PE is HIGH for an even number of HIGH data inputs and PO is HIGH for an odd count. Propagation delay from input to output ranges from 34 ns to 60 ns depending on voltage and temperature conditions.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Simultaneous generation of odd and even parity states for nine data bits
• Expansion capability through cascading multiple units for larger word sizes
• Input clamp diodes enabling interface to voltages exceeding the supply rail

Applications

• Automotive electronic systems requiring parity verification
• Data transmission interfaces utilizing error detection protocols
• Digital logic circuits implementing word-length expansion via cascading

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature grade. Confirm compliance with current automotive qualification standards before integration into safety-critical designs. Review the latest product data sheet revision history to ensure alignment with manufacturing changes or specification updates prior to finalizing procurement orders.

Selection Notes

Select this component when a dedicated 9-bit parity solution is required for CMOS logic environments. Ensure the operating voltage aligns with the 2.0 V to 6.0 V range. Consider cascading capabilities if system architecture demands parity checking for data words exceeding nine bits. Verify thermal management requirements against the specified junction-to-ambient thermal resistance values.

Part Context

This part belongs to the Nexperia 74HC series of high-speed CMOS logic devices. It is specifically designed for automotive applications, meeting rigorous reliability standards set by the Automotive Electronics Council. The device complements other logic families by providing specialized parity functions within a standard small outline package format suitable for surface-mount assembly.

Replacement Considerations

The 74HCT280D-Q100 serves as a functional equivalent within the same family, offering TTL-compatible input levels instead of CMOS levels while maintaining identical pinout and parity functionality.
