SN74AHCT02NSR

Overview

The SN74AHCT02NSR is a quadruple 2-input NOR gate from the Texas Instruments SNx4AHCT02 family, utilizing advanced CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides standard logic outputs with a low-level output current of 8 mA and a high-level output current of -8 mA. Propagation delay is specified at 13 ns. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Advanced CMOS technology ensures high noise immunity and low power consumption.
• TTL-compatible inputs allow direct interfacing with TTL logic sources.
• Wide operating voltage range supports standard 5 V digital systems.
• Industrial temperature rating enables reliable operation in harsh environments.

Applications

• General-purpose logic processing in industrial control systems
• Signal gating and masking in communication equipment

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required package style and tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this component when TTL input compatibility is required alongside CMOS performance benefits. It serves as a suitable alternative to legacy 74LS series parts where lower power dissipation and higher noise margins are necessary for system stability.

Part Context

This part belongs to the SNx4AHCT02 family of quadruple 2-input NOR gates. The AHCT designation indicates High-Speed CMOS technology with TTL-compatible inputs, bridging the gap between older TTL standards and modern low-power CMOS requirements in mixed-logic designs.

Replacement Considerations

Direct functional equivalents include the SN74AHCT02N (DIP package) and SN74AHCT02DR (SOIC package). Verify that substitute packages maintain identical pin configurations and thermal performance for your specific application constraints.
