SN74AHCT02DGVR

Overview

The SN74AHCT02DGVR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the SN74AHCT 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 features four independent NOR gates in a single package. It utilizes a 14-TVSOP surface-mount package. Key electrical characteristics include a propagation delay of 14 ns at 5 V and low static power consumption. The component supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Provides four independent 2-input positive-NOR logic functions
• Ensures compatibility with standard TTL logic levels through AHCT input structures
• Delivers high noise immunity and low power dissipation typical of advanced CMOS technology
• Utilizes a compact 14-pin Thin Visual Small Outline Package (TVSOP) for space-constrained designs

Applications

• Digital signal processing circuits requiring logical NOR operations
• Microcontroller peripheral interface logic
• Consumer electronics control systems
• Industrial communication protocol interfaces

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-14 package and reel packaging configuration. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the operating environment remains within the specified 4.5 V to 5.5 V supply voltage limits to maintain signal integrity and prevent device damage.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance benefits. The AHCT series bridges the gap between older TTL systems and modern low-power CMOS designs. Consider the TVSOP package size relative to available PCB real estate. Evaluate the propagation delay specifications against the maximum clock speeds of the target digital system to ensure timing requirements are met.

Part Context

This part is a member of the Texas Instruments SN74AHC/AHCT family, which represents advanced high-speed CMOS logic. The 'T' suffix indicates TTL-compatible inputs, allowing direct interfacing with legacy 5 V TTL devices without level shifting. This family is widely used in general-purpose digital applications where speed, power efficiency, and compatibility are critical design factors.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include other SN74AHCT02 variants from Texas Instruments or equivalent quad 2-input NOR gates from other manufacturers such as ON Semiconductor or NXP, provided they match the TVSOP-14 footprint and electrical specifications.
