74AC02PC

Overview

The MC74AC02PC is a quad 2-input NOR gate manufactured by onsemi, originally designed by Fairchild Semiconductor. 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. Key electrical parameters include a maximum propagation delay of 6.5ns at 5V with a 50pF load, a typical input capacitance of 4.5pF, and a power dissipation capacitance of 30.0pF. It is housed in a 14-lead Plastic Dual-In-Line Package (PDIP) conforming to JEDEC MS-001 standards.

Feature Summary

• Contains four independent 2-input NOR logic gates
• Outputs provide high drive capability with 24mA source/sink current
• Quiescent supply current reduced by 50% compared to standard AC series

Applications

• General-purpose digital logic circuits
• Timing and control applications
• Signal gating and switching

Procurement Notes

Verify the specific ordering suffix 'PC' corresponds to the 14-lead PDIP package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or material declarations. Ensure the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring low-power CMOS NOR logic with robust output drive capabilities. It is suitable for systems operating between 2V and 6V. Note that while the ACT variant offers TTL-compatible inputs, the AC version requires standard CMOS input thresholds. Verify package availability as the PDIP form factor may have limited production runs compared to surface-mount options.

Part Context

This part belongs to the 74AC02 family of quad 2-input NOR gates. It shares functional compatibility with other members of the 74AC series but differs in packaging. The 'PC' suffix specifically denotes the 14-lead Plastic Dual-In-Line Package (PDIP), distinguishing it from SOIC or TSSOP variants like the SC or MTC suffixes.

Replacement Considerations

Direct pin-compatible substitutes include the 74ACT02 for TTL-compatible input requirements, though voltage ranges differ. Other 74AC02 variants in different packages (e.g., 74AC02SC for SOIC) are functionally equivalent but require layout adjustments.
