SN74AHC02NSR

Overview

The SN74AHC02NSR is a quadruple 2-input positive-NOR gate from the Texas Instruments SNx4AHC02 family, housed in a 14-pin SOP (NS) package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device features low input current of ±1µA and high noise immunity. At VCC = 3.3V, propagation delays are typically 5.6ns with 15pF load and 8.1ns with 50pF load. At VCC = 5V, delays are typically 3.6ns (15pF) and 5.1ns (50pF). Output drive capabilities include ±8mA at 5V and ±4mA at 3.3V.

Feature Summary

• Contains four independent 2-input NOR gates performing Boolean logic Y = A + B
• CMOS technology ensures low static power consumption and high noise immunity
• Compatible with standard CMOS logic families across wide voltage ranges
• Robust latch-up performance exceeding specified JESD standards

Applications

• General-purpose digital logic processing
• Signal gating and control circuits
• Industrial control systems requiring wide temperature operation
• Consumer electronics utilizing 3.3V or 5V logic levels

Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP-14 package and tape-and-reel carrier format. Confirm RoHS compliance status and lead finish details via the latest Package Option Addendum. Ensure the procurement channel sources parts directly from Texas Instruments or authorized distributors to guarantee authenticity and traceability for production environments.

Selection Notes

Select this component when designing circuits requiring multiple independent NOR functions in a single surface-mount package. The AHC series offers faster switching speeds compared to legacy HC devices while maintaining compatibility. Consider the NS package dimensions for PCB layout constraints and verify that the required propagation delay specifications align with the system clock speeds at the intended operating voltage.

Part Context

This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates. The 'SN74' prefix indicates commercial grade availability, while 'AHC' denotes advanced high-speed CMOS technology. The 'NS' suffix specifies the Small Outline Package (SOP), and 'R' indicates reel packaging. This family provides a modern replacement for older logic families in mixed-voltage applications.

Replacement Considerations

Direct pin-compatible alternatives within the same family include SN74AHC02DR (SOIC D package) and SN74AHC02PWR (TSSOP PW package). For automotive applications, consider the SN74AHC02-Q1 variant. Verify thermal resistance values as they vary significantly between package types such as DB, DGV, and NS.
