74HC05D,112

Overview

The Nexperia 74HC05D,112 is a hex inverter with open-drain outputs housed in an SOIC-14 package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports temperatures from -40 °C to +125 °C. The device features CMOS input levels and complies with JEDEC standard no. 7A. Propagation delays are specified at 90 ns maximum for 2.0 V operation and 27 ns maximum for 4.5 V operation.

Feature Summary

• Open-drain outputs enable active-LOW wired-OR or active-HIGH wired-AND logic functions when connected together.
• High noise immunity and low power dissipation characteristics inherent to the CMOS technology.
• Robust ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.

Applications

• Implementing wired-logic configurations using pull-up resistors
• Driving high-voltage loads through external circuitry
• General-purpose signal inversion in digital logic circuits

Procurement Notes

Verify component authenticity against official Nexperia documentation before integration. Confirm that the SOIC-14 package variant matches your PCB footprint requirements. Ensure operating conditions remain within the specified voltage and temperature limits to maintain performance reliability.

Selection Notes

Select this component when open-drain output capability is required for bus sharing or level shifting. Verify that the HC series speed and voltage compatibility align with the system design constraints. Consider the thermal derating specifications if operating near the upper temperature limit.

Part Context

This part belongs to the 74HC05 family of hex inverters. The 'D' suffix indicates the SOIC-14 plastic small outline package. The ',112' suffix denotes the specific tube packaging configuration used by Nexperia for distribution.

Replacement Considerations

The IKSEMI IN74HC05ADT is documented as a direct pin-to-pin replacement option for the 74HC05D.
