Overview
The SN74AHC02PWRG4 is a Texas Instruments quadruple 2-input positive-NOR gate in the AHC logic series. It operates within a supply voltage range of 2V to 5.5V and features latch-up performance exceeding 250mA per JESD 17. The device utilizes a 14-pin TSSOP (PW) package with a body size of 5.00mm x 4.4mm. Recommended operating conditions specify an ambient temperature range of -40°C to +125°C. Electrical characteristics include high-level output currents up to -8mA at 5V and low-level output currents up to 8mA at 5V.
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 specified current limits
Applications
- General-purpose digital logic signal processing
- Boolean logic implementation in electronic circuits
- Signal gating and control applications
Procurement Notes
Verify the specific ordering suffix 'G4' against the manufacturer's current documentation to confirm material composition, lead finish, and environmental compliance status. Ensure the selected package variant matches the required thermal and mechanical constraints for the target PCB layout. Cross-reference the active production status with the latest Package Option Addendum before finalizing procurement plans.
Selection Notes
Select this component when a quad 2-input NOR function is required within the AHC family specifications. The TSSOP-14 package offers a compact surface-mount solution suitable for space-constrained designs. Verify that the input transition rates and load capacitance requirements align with the switching characteristics defined in the datasheet for the intended operating voltage.
Part Context
This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates manufactured by Texas Instruments. The family includes various package options such as SOIC, SSOP, TVSOP, PDIP, SOP, VQFN, and WQFN. The SN74AHC02 represents the commercial grade version, distinct from the military-grade SN54AHC02 or automotive-qualified variants.
Replacement Considerations
Direct pin-compatible alternatives within the same family include SN74AHC02DR, SN74AHC02DBR, and SN74AHC02DGVR. Non-TI equivalents may require verification of logic compatibility and electrical parameter alignment.
