74F280SJX

Overview

The onsemi 74F280SJX 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 parity states. The device features Sum Even and Sum Odd outputs, where the Sum Even output goes HIGH if an even number of inputs are HIGH. Recommended operating conditions specify a supply voltage range of +4.5V to +5.5V and an ambient temperature range of 0°C to +70°C.

Feature Summary

• Performs 9-bit parity generation and checking functions
• Provides complementary Sum Even and Sum Odd outputs
• Operates within standard TTL logic voltage levels

Applications

• Data transmission error detection systems
• Memory unit parity verification circuits
• Digital communication interface protocols

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package markings match the 14-lead SOP specification. Review datasheet electrical characteristics for compatibility with system voltage requirements. Ensure storage conditions adhere to specified humidity and temperature limits to maintain device integrity prior to assembly.

Selection Notes

Select this component when 9-bit parity processing is required within standard logic families. Verify that the 14-lead SOP footprint aligns with PCB layout constraints. Check propagation delay specifications against system timing requirements. Confirm that the operating temperature range meets environmental design criteria.

Part Context

This part belongs to the 74F series of high-speed CMOS logic devices originally manufactured by Fairchild Semiconductor. The 'SJX' suffix indicates the specific 14-lead SOP package configuration with tape and reel availability. The device serves as a specialized logic function block for digital signal integrity applications.

Replacement Considerations

Cross-reference with other 74F280 variants from different manufacturers. Verify pinout compatibility and electrical parameter equivalence. Ensure package dimensions match existing board space constraints before substitution.
