74AC02SJ

Overview

The onsemi 74AC02SJ is a Quad 2-Input NOR gate housed in a 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features outputs capable of sourcing and sinking 24mA. Propagation delays are specified at 6.5ns maximum at 5.0V with a 50pF load.

Feature Summary

• Contains four independent 2-input NOR logic gates
• Outputs provide high drive capability for direct load interfacing
• Compatible with standard CMOS logic families

Applications

• General-purpose digital logic circuits
• Signal gating and switching applications
• Data acquisition systems

Procurement Notes

Verify the specific package variant against the ordering number suffix 'SJ' to ensure compatibility with the 5.3mm wide SOP footprint. Confirm that the application environment remains within the recommended operating temperature and voltage limits defined in the datasheet to maintain performance specifications.

Selection Notes

Select this component when a quad NOR configuration is required in a narrow SOP package. Ensure the design accounts for the 24mA output current capability and verify input threshold levels match the system voltage rails. Consider the propagation delay characteristics relative to the system clock speed.

Part Context

This part belongs to the 74AC series of high-speed CMOS logic devices. It serves as a fundamental building block for complex digital designs, offering improved speed over older 74LS equivalents while maintaining low power consumption. The SOP package provides a compact solution for surface-mount assembly.

Replacement Considerations

Check for cross-manufacturer equivalents such as Fairchild or ON Semiconductor variants with identical electrical characteristics and pinouts. Verify package dimensions if substituting with other SOP types.
