Overview
The SN74AHC02PWR is a quadruple 2-input positive-NOR gate from the Texas Instruments AHC logic family, 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 low input current and high noise immunity typical of CMOS technology. At VCC = 5V, it delivers a low-level output current of 8mA and a high-level output current of -8mA. Propagation delay is typically 5.1ns at VCC = 5V with a 50pF 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 latch-up performance exceeding 250mA per JESD 17-1 standard
Applications
- General-purpose digital logic processing
- Signal gating and control circuits
- Portable battery-powered systems requiring low power consumption
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package and tape-and-reel carrier configuration. Confirm RoHS compliance and lead finish details (NIPDAU) against the latest Package Option Addendum. Ensure the procurement request matches the active production status for this specific variant.
Selection Notes
Select this component when a quad NOR gate functionality is required in space-constrained designs utilizing surface-mount assembly. The TSSOP-14 package offers a compact footprint suitable for high-density PCB layouts. Consider the 2V to 5.5V operating range for compatibility with various logic levels and power domains.
Part Context
This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates. The 'SN74' prefix indicates commercial grade specifications, while the 'AHC' series denotes advanced High-speed CMOS technology. The 'PW' suffix specifically identifies the Thin Shrink Small Outline Package (TSSOP) variant within the broader product line.
Replacement Considerations
Direct pin-compatible alternatives include other packages within the same SN74AHC02 family such as SN74AHC02DR (SOIC) or SN74AHC02DBR (SSOP). Verify that any substitute maintains the TSSOP-14 form factor if board space is constrained.
