74AC280SJX

Overview

The onsemi 74AC280SJX is a high-speed 9-bit parity generator and checker housed in a 14-lead Small Outline Package (SOP). It accepts nine data inputs to detect even or odd input states, providing complementary Sum Even and Sum Odd outputs. The device operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature range from -40°C to +85°C. Propagation delays are specified at 13.0ns maximum for the Sum Even output and 14.5ns maximum for the Sum Odd output at 5.5V.

Feature Summary

• Generates and checks parity for nine-bit data streams
• Provides complementary Sum Even and Sum Odd outputs
• Optimized for memory applications with reduced ICC

Applications

• Memory systems requiring parity checking
• Data transmission error detection circuits
• Digital logic systems utilizing 9-bit word structures

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package markings match the 14-lead SOP format. Ensure environmental compliance documentation aligns with project requirements. Validate that the specific ordering suffix corresponds to the tape and reel packaging configuration if applicable.

Selection Notes

Select this component when a 9-bit width is required for parity generation or checking. Consider the AC series speed characteristics and the 14-lead SOP footprint for board layout compatibility. Verify that the input voltage thresholds and propagation delay specifications meet the system timing constraints.

Part Context

This part belongs to the 74AC logic family, known for high-speed CMOS performance. It functions as a single-function gate specialized for parity operations. The device integrates nine input channels into a compact surface-mount package suitable for dense circuit designs.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives. Verify electrical parameters such as propagation delay and output current capabilities before substitution.
