Overview
The 74AHCT02PW,112 is a quad 2-input NOR gate manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and features TSSOP-14 packaging. The device provides non-inverting logic functionality with three-state outputs. Key electrical parameters include a propagation delay of 8.4 ns at 4.5 V to 5.5 V, high-level output current of -8 mA, and low-level output current of 8 mA. Static current is specified at 4 uA, with a maximum operating temperature of +125 C.
Feature Summary
- Quad 2-input NOR gate configuration for complex logic implementation
- Three-state output capability for bus-oriented systems
- CMOS technology ensuring low static power consumption
Applications
- Digital signal processing circuits requiring NOR logic functions
- Microprocessor-based systems for address decoding
- Memory interface circuits utilizing bus tri-state control
Procurement Notes
Verify the manufacturer designation carefully, as sources may list NXP Semiconductors or Nexperia USA Inc. due to corporate history. Confirm the package type is TSSOP-14 and the logic family is AHCT. Check for obsolescence status, as some listings indicate end-of-life conditions. Ensure the ordering suffix matches the required tape and reel or tube quantity specifications.
Selection Notes
Select this component when a quad 2-input NOR function is required in CMOS logic designs. The AHCT series ensures compatibility with TTL input levels while operating at standard CMOS voltages. Consider the TSSOP-14 package for space-constrained PCB layouts. Verify that the 8.4 ns propagation delay meets the timing requirements of the target application circuit.
Part Context
This part belongs to the 74AHCT logic family, which combines high-speed CMOS performance with TTL-compatible inputs. The 74AHCT02 specifically implements four independent 2-input NOR gates. It is designed for applications requiring reliable logic switching in digital environments. The PW suffix indicates the TSSOP surface-mount package variant.
Replacement Considerations
Compatible substitutes include other 74AHCT02 variants from different manufacturers offering identical pinouts and logic functions. Verify that replacement parts maintain the same TSSOP-14 package dimensions and electrical characteristics. Cross-reference datasheets to ensure equivalent propagation delays and output drive capabilities.
