74HC05S14-13

Overview

The 74HC05S14-13 is a hex inverter with open drain outputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 6.0V and features Schmitt trigger inputs for noise immunity. The device provides six independent inverters in a 14-pin SOIC package, designed for surface mount applications.

Feature Summary

• Hex inverters with open drain outputs
• Schmitt trigger action at all inputs
• CMOS low power consumption
• ESD protection exceeding JESD 22 standards

Applications

• General purpose logic
• PCs and networking equipment
• Notebooks and netbooks
• Computer peripherals and hard drives
• TV, DVD, DVR, and set top boxes

Procurement Notes

Verify the specific package variant (SO-14 or TSSOP-14) matches the design requirements. Confirm RoHS compliance and halogen-free status if required by environmental regulations. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component when open drain outputs are required for wired-AND configurations or level shifting. The Schmitt trigger inputs provide improved noise immunity compared to standard inverters. Verify that the load current does not exceed the 4mA sink capability at 4.5V.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally similar to other hex inverters but distinguished by its open drain output structure, which allows for interfacing with different voltage domains.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers that offer open drain outputs. Ensure any substitute maintains the same Schmitt trigger input characteristics and operating voltage range.
