Procurement Notes

Verify the manufacturer designation as Toshiba Semiconductor and Storage when sourcing this component. Confirm that the package type matches the required SOIC-14 footprint. Ensure the selected variant meets the specific temperature and voltage requirements for your application environment before finalizing procurement.

Selection Notes

Select the 74HC05D when open-drain outputs are necessary for wired-AND operations or level shifting. This device is suitable for applications requiring high-speed switching with low quiescent current. Consider the maximum load capacitance and pull-up resistor values to ensure signal integrity and proper switching speeds.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic integrated circuits. It serves as the open-drain counterpart to the standard 74HC04 hex inverter. The device utilizes advanced C2MOS technology to achieve performance levels similar to older LSTTL families while maintaining the low power advantages inherent to CMOS designs.

Replacement Considerations

The Nexperia 74HC05D,112 is a confirmed substitute part number offering equivalent functionality.
