SN74AHCT02N

Overview

The SN74AHCT02N is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the AHCT logic series, designed for CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a 14-pin DIP package. It functions reliably across an extended temperature range from -40°C to +85°C, providing four independent NOR logic channels.

Feature Summary

• Integrates four independent 2-input NOR logic gates within a single integrated circuit.
• Features TTL-compatible input thresholds allowing direct interfacing with TTL logic systems.
• Utilizes advanced CMOS technology to ensure low power consumption during operation.

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing in industrial control systems
• Consumer electronics utilizing standard logic families

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature rating. Ensure the component matches the required logic family specifications for your design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a quadruple 2-input NOR function is required with TTL-compatible input levels. It is suitable for designs operating at 5V with standard through-hole assembly constraints. Consider alternative packages if surface-mount space is limited or if different voltage ranges are necessary for the application environment.

Part Context

This component is part of the SN74AHCTxx series, which bridges CMOS performance with TTL compatibility. The '02' designation specifically identifies the NOR logic function within the Texas Instruments portfolio. It serves as a fundamental building block for complex digital logic designs requiring reliable signal gating in standard voltage environments.
