SN74HC05DT

Overview

The SN74HC05DT is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the HC logic series. It features six independent inverters with open-drain outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40 °C to +85 °C. Designed as a high-speed Si-gate CMOS component, it complies with JEDEC standard no. 7A and provides robust latch-up performance exceeding 100 mA per JESD 78 Class II level.

Feature Summary

• Hex inverter configuration with open-drain outputs suitable for wired-OR or wired-AND implementations
• High-speed Si-gate CMOS technology ensuring fast switching capabilities
• Robust ESD protection meeting HBM JESD22-A114E (exceeds 2000 V) and CDM JESD22-C101C (exceeds 1000 V) standards

Applications

• Signal inversion in digital logic circuits
• Implementing active-LOW wired-OR functions via open-drain output connection
• Implementing active-HIGH wired-AND functions via open-drain output connection

Procurement Notes

Verify the specific manufacturer datasheet for the SN74HC05DT to confirm exact electrical characteristics and pinout configurations. Ensure the selected component matches the required 14-SOIC package dimensions and thermal specifications for your application environment. Cross-reference official documentation to validate compliance with relevant JEDEC standards and ESD protection ratings before integration.

Selection Notes

Select this component when a hex inverter with open-drain outputs is required for interfacing different voltage levels or implementing bus structures. The HC series offers compatibility with standard CMOS logic levels across a broad voltage range. Consider the 14-SOIC package for surface-mount assembly needs and verify that the operating temperature range meets the environmental requirements of the target system.

Part Context

This part belongs to the widely used 74HC05 family of hex inverters with open-drain outputs. Similar variants include the SN74HC05N (PDIP package) and SN74HC05DR (SOIC package). These components are standard general-purpose logic devices designed for applications requiring signal inversion and open-collector/open-drain functionality within industrial and consumer electronic systems.

Replacement Considerations

Direct substitutes include SN74HC05DR and SN74HC05N from Texas Instruments. Other manufacturers offer equivalent parts such as the NXP 74HC05 or STMicroelectronics M74HC05RM13TR, provided pinouts and electrical specifications align.
