Overview
The SN74AHC02DBR is a quadruple 2-input positive-NOR gate from the Texas Instruments AHC logic family, housed in a 14-pin SSOP 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 provides high-level output currents up to -8mA and low-level output currents up to 8mA at 5V. Propagation delays are specified as 8.5ns maximum at 5V with 50pF load, and 11.4ns maximum at 3.3V with 50pF load.
Feature Summary
- Contains four independent 2-input NOR gates performing Boolean function Y = A + B
- CMOS technology ensures low static power consumption and wide operating voltage range
- Latch-up performance exceeds 250mA per JESD 17 specifications
Applications
- General-purpose digital logic signal processing
- Boolean logic implementation in embedded systems
- Signal gating and control circuits
Procurement Notes
Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel carrier format. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the procurement source provides valid traceability documentation for the production lot.
Selection Notes
Select this component when a quad NOR gate configuration is required within the AHC speed and voltage parameters. Verify that the 14-pin SSOP footprint matches the PCB layout constraints. Consider thermal resistance characteristics if multiple devices operate simultaneously in confined spaces.
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' series denotes advanced high-speed CMOS technology compatible with standard TTL inputs. The 'DBR' suffix specifies the surface-mount SSOP package variant.
Replacement Considerations
Direct pin-compatible alternatives include other manufacturers' SN74AHC02 variants in SSOP-14 packages. Verify logic truth tables and electrical characteristics such as propagation delay and output drive current before substitution.
