74HCT280D-Q100J

Overview

The Nexperia 74HCT280D-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 4.5 V to 5.5 V, with a typical operating voltage of 5.0 V. The device features TTL input levels and provides complementary even (PE) and odd (PO) parity outputs. It is qualified to AEC-Q100 Grade 1 standards for automotive applications and supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Generates or checks both odd and even parity for nine data bits
• Word-length expansion capability through cascading parallel devices
• High noise immunity with latch-up performance exceeding 100 mA

Applications

• Automotive electronic systems requiring parity verification
• Data transmission error detection circuits
• Digital communication interface integrity monitoring
• Industrial control system data validation

Procurement Notes

Verify the specific suffix J indicates reel packaging configuration before ordering. Confirm current production status directly with Nexperia as availability may vary. Ensure the selected component matches the required AEC-Q100 Grade 1 qualification level for your specific automotive application environment.

Selection Notes

Select this part when a 9-bit parity solution with TTL-compatible inputs is required. The HCT series ensures compatibility with standard TTL logic families while offering CMOS low power dissipation. Consider cascading multiple units if word sizes exceed nine bits. Verify that the SO14 package dimensions fit your PCB layout constraints.

Part Context

This component belongs to the Nexperia 74HCT280-Q100 family of logic ICs designed for robust digital signal processing. It serves as a specialized function block within larger microcontroller or FPGA peripheral systems where hardware-level data integrity checking is essential without software overhead.

Replacement Considerations

The 74HC280D-Q100J is a compatible alternative but utilizes CMOS input levels rather than TTL. Verify voltage compatibility and input threshold requirements before substituting HC variants for HCT versions in existing designs.
