- Industrial control applications
Procurement Notes
Verify the specific ordering code 74HC21PW,112 against official Nexperia documentation to ensure correct package type and tape/reel specifications. Confirm compliance requirements such as RoHS and REACH status directly from the manufacturer's datasheet or chemical content declaration before procurement. Check current product availability status as manufacturing lifecycles may change.
Selection Notes
Select this component when a dual 3-input AND function is required in CMOS logic designs. Ensure the operating voltage aligns with the HC series specifications. Consider the TSSOP package dimensions for PCB layout constraints. Verify input compatibility with system voltage levels and check ESD protection ratings if sensitive environments are involved.
Part Context
This part is part of the standard 74HC logic family, widely used for general-purpose digital logic functions. It offers a balance between speed and power consumption suitable for battery-powered and general electronic equipment. The PW suffix indicates a TSSOP plastic weakly leaded small outline package.
Replacement Considerations
Compatible replacements include other manufacturers' 74HC21 equivalents in TSSOP packages. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current. Cross-reference with Nexperia's official replacement list for any direct substitutes.
