SN74HC05ANS

Overview

The SN74HC05ANS is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74HC 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 an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 20 ns at 6 V with a 50 pF load, and output drive capabilities of ±4 mA for both high and low states.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• Open-drain output architecture suitable for wired-OR connections and level shifting
• CMOS technology ensuring low static power consumption and high noise immunity

Applications

• General-purpose digital signal inversion in microcontroller interfacing circuits
• Level translation between different voltage domains using open-drain topology
• Bus driver applications requiring wired-AND or wired-OR logic implementation

Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides valid RoHS compliance documentation as required for modern electronic assemblies. Cross-reference the ordering part number with the latest Texas Instruments product selection guide to avoid obsolete variants.

Selection Notes

Select this component when a standard hex inverter with open-drain outputs is required for CMOS logic applications. The 74HC series offers speed comparable to LS TTL while maintaining lower power consumption. Consider the open-drain feature specifically if the design requires driving loads at voltages higher than the logic supply or necessitates multiple outputs sharing a common line.

Part Context

This component belongs to the widely adopted 74HC family of high-speed CMOS logic devices. The HC series is designed to be compatible with standard TTL logic levels while offering improved performance over older NMOS technologies. The SN74HC05 variant specifically adds open-drain outputs, distinguishing it from the standard push-pull SN74HC04, making it unique for specific interface requirements.

Replacement Considerations

Direct functional substitutes include the SN74HC05DR (SOIC-14) and SN74HC05N (PDIP-14). Verify that replacement parts maintain the open-drain output characteristic, as standard inverters like the SN74HC04 use push-pull outputs which are not electrically equivalent for open-drain applications.
