Overview
The SN74AHC02PW is a quadruple 2-input positive-NOR gate from the Texas Instruments AHC series, housed in a 14-pin TSSOP 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 latch-up performance exceeding 250mA per JESD 17 and provides high-level output current of -8mA and low-level output current of 8mA at 5V. Propagation delays are typically 3.6ns at 5V with 15pF load.
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 per JESD 17 standard
Applications
- General-purpose digital logic signal processing
- Boolean logic implementation in embedded systems
- Signal routing and gating in consumer electronics
Procurement Notes
Verify the specific ordering suffix 'PW' corresponds to the TSSOP-14 package variant. Confirm RoHS compliance status and lead finish details via the latest Package Option Addendum. Ensure the procurement channel sources production data directly from Texas Instruments or authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component for designs requiring quad NOR functionality within the AHC family's speed and voltage specifications. Consider the TSSOP-14 package constraints regarding thermal resistance and board space. Evaluate if the 2V to 5.5V operating range aligns with the system power rails and if the -40°C to +125°C temperature range meets environmental requirements.
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 'PW' suffix specifically identifies the Thin Shrink Small Outline Package (TSSOP) with 14 pins, distinguishing it from SOIC, SSOP, or VQFN variants.
Replacement Considerations
Direct pin-compatible alternatives include SN74AHC02PWR (same package, tape & reel), SN74AHC02DR (SOIC package), and SN74AHC02DBR (SSOP package). Verify package dimensions and thermal characteristics when substituting between different package types.
