Overview
The SN74AHC02D is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments in a 14-pin SOIC package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range from -40°C to 125°C. The device provides high-level output currents of up to -8mA and low-level output currents of up to 8mA at 5V. Propagation delays are typically 3.6ns at 5V with 15pF load, rising to 5.1ns maximum under the same conditions.
Feature Summary
- Contains four independent 2-input NOR gates performing Boolean function Y = A + B
- Latch-up performance exceeds 250mA per JESD 17 standard
- Provides ESD protection rated at ±2000V for human-body model and ±1000V for charged-device model
Applications
- General-purpose digital logic circuits requiring NOR functionality
- Signal processing applications utilizing wide voltage operation
- Industrial control systems operating across extended temperature ranges
Procurement Notes
Verify the specific ordering suffix against the Package Option Addendum to confirm current production status. The 'SN74AHC02D' designation without a trailing letter indicates an obsolete status; active versions include 'DR' or 'DBR'. Confirm RoHS compliance and moisture sensitivity level ratings prior to procurement to ensure compatibility with assembly processes.
Selection Notes
Select this component when four independent NOR gates are required in a single package. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power consumption. Ensure the design accommodates the specified input transition rates and output drive capabilities for the target supply voltage.
Part Context
This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates. The 'D' suffix denotes the 14-pin Small Outline Integrated Circuit (SOIC) package variant. Other available packages in this family include SSOP, TVSOP, PDIP, SOP, VQFN, and WQFN configurations.
Replacement Considerations
The SN74AHC02D is listed as obsolete. Active replacements include SN74AHC02DR (SOIC-14 Tape & Reel) and SN74AHC02DBR (SSOP-14 Tape & Reel). Verify pinout compatibility and thermal characteristics when transitioning between these variants.
