74ACT02PC

Overview

The onsemi 74ACT02PC is a Quad 2-Input NOR Gate manufactured in a 14-Lead Plastic Dual-In-Line Package (PDIP). It operates within a supply voltage range of 4.5V to 5.5V and an ambient temperature range of -40°C to +85°C. The device features TTL-compatible inputs, with minimum HIGH level input voltage at 2.0V and maximum LOW level input voltage at 0.8V. Outputs can source or sink up to 24mA. Propagation delays are typically 6.0ns for high-to-low and 6.5ns for low-to-high transitions at 5.0V.

Feature Summary

• Contains four independent 2-input NOR logic gates
• Features TTL-compatible input thresholds for direct interfacing
• Provides strong output drive capability with 24mA source/sink current

Applications

• Digital logic circuit design
• Timing and control circuits
• Signal processing applications

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel availability. Ensure compliance with JEDEC lead-free standards. Confirm that the component meets the required operating temperature and voltage specifications for the intended application environment before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside standard CMOS performance levels. The PDIP package is suitable for through-hole mounting. Consider the ACT series for improved speed over AC variants while maintaining compatibility with existing TTL logic families.

Part Context

This part belongs to the 74AC/ACT logic family, which combines the high speed of advanced CMOS technology with the noise immunity of standard CMOS. The ACT variant specifically adds TTL-compatible inputs, facilitating easier integration into systems utilizing legacy TTL components.

Replacement Considerations

Check for equivalent parts from other manufacturers such as MC74ACT02PC. Verify pinout compatibility and electrical characteristics match the original datasheet requirements.
