SN74HC05ANSR

Overview

The SN74HC05ANSR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the HC logic family. 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. Key electrical characteristics include a propagation delay of 32 ns at 5 V 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 structure suitable for wired-OR applications and level shifting
• CMOS technology ensuring low power consumption and high noise immunity
• Wide supply voltage operation compatible with standard digital logic systems

Applications

• Signal buffering and inversion in digital control circuits
• Level translation between different voltage domains
• Wired-OR logic implementation in bus structures
• General-purpose switching applications in consumer electronics

Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the SOIC-14 tape-and-reel packaging variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with open-drain output requirements, as this component lacks internal pull-up resistors. Validate thermal performance specifications against intended operating conditions.

Selection Notes

Select this component when hex inversion with open-drain outputs is required. Compare against SN74HC04ANSR if push-pull outputs are preferred instead of open-drain. Consider SN74HCT05ANSR for direct TTL interface compatibility. Evaluate package constraints to ensure SOIC-14 footprint matches PCB layout requirements. Verify voltage levels match system supply rails within the 2 V to 6 V operational range.

Part Context

This part belongs to the Texas Instruments SN74HC series of high-speed CMOS logic devices. The HC series offers improved speed and lower power consumption compared to older LS or ALS families. The SN74HC05 specifically provides open-drain outputs, distinguishing it from standard push-pull inverters like the SN74HC04. It is designed for general-purpose digital applications requiring reliable signal inversion.

Replacement Considerations

SN74HC04ANSR serves as a functional substitute if push-pull outputs are acceptable instead of open-drain. SN74HCT05ANSR may be used where TTL input thresholds are required. Cross-reference datasheets for pinout and electrical parameter compatibility before substitution.
