SN74AHCT02PWR

Overview

The SN74AHCT02PWR is a quad 2-input NOR gate from the Texas Instruments SN74AHCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TSSOP-14 packaging. The device supports low-level output currents of 8 mA and high-level output currents of -8 mA. Propagation delay is specified at 7.5 ns. Operating temperatures extend from -40°C to +85°C.

Feature Summary

• Provides four independent 2-input NOR logic functions in a single package
• Compatible with standard 5-V CMOS logic families through AHCT input structures
• Designed for surface-mount assembly using TSSOP-14 footprint

Applications

• Digital signal processing circuits requiring NOR logic operations
• Microcontroller peripheral interface logic
• General-purpose digital control systems

Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-14 package configuration. Confirm the AHCT designation ensures compatibility with 5-V CMOS inputs. Check RoHS compliance status as indicated in official documentation. Ensure the operating temperature range meets system requirements before procurement.

Selection Notes

Select this component when four independent NOR gates are required in a compact surface-mount form factor. The AHCT series ensures compatibility with 5-V logic levels, making it suitable for interfacing with standard CMOS devices. Consider the propagation delay and output drive capabilities relative to circuit speed requirements.

Part Context

This part belongs to the SN74AHCT family of advanced high-speed CMOS logic devices. The family offers high-speed operation while maintaining compatibility with standard 5-V CMOS inputs. The SN74AHCT02 specifically implements NOR logic functions, distinguishing it from NAND or OR variants within the same series.

Replacement Considerations

Check for SN74AHCT02RGVR or similar TI variants with compatible packages. Verify cross-brand equivalents such as those from ON Semiconductor or NXP that match the AHCT specification and TSSOP-14 footprint.
