74HC05D,118

Overview

The Nexperia 74HC05D,118 is a hex inverter with open-drain outputs housed in an SO14 (SOT108-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels and complies with JEDEC standard no. 7A. Static characteristics include an input leakage current of ±1 μA at 6.0 V and a supply current of up to 40 μA under maximum temperature conditions.

Feature Summary

• Open-drain output configuration enabling active-LOW wired-OR or active-HIGH wired-AND logic functions when connected together.
• High ESD protection capability exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model.
• Robust latch-up performance that exceeds 100 mA per JESD 78 Class II level A standards.

Applications

• Implementing wired-logic configurations requiring pull-up resistors
• Signal inversion in CMOS digital circuits
• Level shifting applications compatible with wide voltage ranges

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC05 series includes TSSOP and DHVQFN variants. Confirm the temperature grade aligns with system requirements, noting the D variant supports extended industrial ranges. Ensure compliance with RoHS and REACH directives is documented for your manufacturing process.

Selection Notes

Select this component when open-drain outputs are necessary for wired-logic implementation or bus sharing. The wide operating voltage range accommodates mixed 5 V and 3.3 V systems. Verify that external pull-up resistors are included in the design, as the internal structure requires them for correct HIGH-state operation.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices manufactured by Nexperia. The HC series is designed for general-purpose digital applications, offering compatibility with standard TTL inputs while maintaining low power consumption. The 74HC05 specifically provides six independent inverters within a single integrated circuit package.

Replacement Considerations

Check for equivalent parts such as the 74HC05PW (TSSOP14) or 74HC05BQ (DHVQFN14) if different packaging is required. Ensure any substitute maintains the open-drain output characteristic and meets the same voltage and temperature specifications.
