Procurement Notes

Verify the specific ordering suffix 'AUJ' against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage levels and load requirements before procurement. Confirm that the component meets all necessary environmental and safety standards for the intended application.

Selection Notes

Select this component when a quad 2-input OR gate is required with wide supply voltage flexibility between 2.0 V and 6.0 V. Consider its TSSOP14 package for surface-mount applications where space efficiency is needed. Evaluate its propagation delay characteristics against system timing requirements to ensure signal integrity.

Part Context

This part belongs to the 74HC series of high-speed silicon-gate CMOS devices. It is pin-compatible with low-power Schottky TTL (LSTTL) families, facilitating direct replacement in legacy designs. The 74HC32 provides four independent OR gates in a single package, offering a compact solution for complex logic implementations.

Replacement Considerations

Direct replacements include other 74HC32 variants from different manufacturers such as ON Semiconductor or Diodes Incorporated, provided they meet the same electrical specifications and package dimensions. Verify pinout compatibility and operating conditions before substitution.
