Overview
The SN74HC02PWRG4 is an automotive-grade, quad 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic family and operates within a supply voltage range of 2 V to 6 V. The device features four independent NOR gates, each with two inputs and one output. Key electrical parameters include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. Propagation delay is specified at 18 ns. It supports surface-mount installation in a TSSOP-14 package and meets AEC-Q100 qualification standards for operation between -40°C and +125°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Wide operating temperature range suitable for harsh environments
- CMOS technology ensures low static power consumption
Applications
- Automotive electronic control units
- In-vehicle communication systems
- Industrial process control logic
Procurement Notes
Verify that the specific part number suffix matches the required automotive grade and package variant. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure design compatibility with the specified voltage and temperature ranges for target applications.
Selection Notes
Select this component when automotive certification and extended temperature performance are mandatory requirements. Compare propagation delay and output drive capabilities against system timing constraints. Verify package dimensions and pinout compatibility during PCB layout planning.
Part Context
This component is part of the SN74HC02 series, which provides quad 2-input NOR logic functions. The 'QPWRG4' designation indicates automotive qualification, TSSOP packaging, and lead-free composition. It serves as a fundamental building block for complex digital logic circuits requiring robust environmental tolerance.
Replacement Considerations
Cross-reference with other automotive-qualified HC-series NOR gates from Texas Instruments or compatible manufacturers. Ensure functional equivalence regarding logic type, package footprint, and electrical specifications before substitution.
