Overview
The SN74AHC02DR is a quadruple 2-input positive-NOR gate from the AHC logic series, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features latch-up performance exceeding 250mA per JESD 17. The device provides high output drive capabilities with ±8mA at 5V and low static current consumption. It supports an operating temperature range of -40°C to +125°C and includes ESD protection ratings of ±2000V (HBM) and ±1000V (CDM). Packaged in a 14-pin SOIC (D) format, it delivers switching characteristics suitable for general-purpose digital applications.
Feature Summary
- Contains four independent 2-input NOR gates performing Boolean function Y = A + B
- Operates across a wide supply voltage range from 2V to 5.5V
- Provides robust latch-up protection exceeding 250mA according to JESD 17 standards
Applications
- General-purpose digital logic circuits requiring NOR functionality
- Signal processing systems utilizing CMOS logic families
- Industrial control environments operating between -40°C and +125°C
Procurement Notes
Verify the specific ordering suffix 'DR' corresponds to the SOIC-14 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish details via the latest Package Option Addendum. Ensure design compatibility with the specified thermal resistance and moisture sensitivity level before finalizing procurement specifications.
Selection Notes
Select this component when a quad 2-input NOR gate is required within the AHC family. It is appropriate for designs needing operation up to 5.5V with standard SOIC surface-mount packaging. Consider alternative packages like SSOP or VQFN if board space constraints differ from the SOIC dimensions provided in the datasheet.
Part Context
This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates. The 'SN74' prefix indicates commercial grade availability, while the 'AHC' designation specifies Advanced High-Speed CMOS technology. The 'DR' suffix identifies the specific 14-pin Small Outline Integrated Circuit package variant produced by Texas Instruments.
Replacement Considerations
Direct substitutes include other SN74AHC02 variants such as SN74AHC02DBR (SSOP) or SN74AHC02DGVR (TVSOP), provided pinout compatibility is verified. Cross-family replacements require careful evaluation of voltage levels and propagation delays.
