SN74LS05N

Inverter Gates Overview

The SN74LS05N is a hex inverter integrated circuit from Texas Instruments, belonging to the 74LS logic family. It features six independent inverters with open-collector outputs, housed in a 14-pin PDIP package for through-hole mounting. The device operates within a supply voltage range of 4.75V to 5.25V and supports a wide operating temperature range from 0°C to +70°C. Key electrical characteristics include a maximum propagation delay of 32ns at 5V with 15pF load capacitance, a low-level output current capability of 8mA, and TTL input/output compatibility.

Inverter Gates Feature Summary

• Contains six independent inverting channels providing signal inversion functionality
• Features open-collector outputs suitable for wired-AND configurations and voltage level shifting
• Compatible with standard TTL logic families for seamless integration

Inverter Gates Applications

• General-purpose digital logic inversion circuits
• Wired-AND bus line implementations requiring open-collector topology
• Voltage level translation between different logic domains

Inverter Gates Procurement Notes

Verify the specific suffix 'N' confirms the plastic dual-in-line package (PDIP) and through-hole construction. Confirm the manufacturer is Texas Instruments to ensure compliance with original specifications. Check RoHS status as revisions may vary. Ensure the application environment remains within the specified 0°C to +70°C temperature range and 4.75V to 5.25V supply voltage limits for reliable operation.

Inverter Gates Selection Notes

Select this component when six independent inverters with open-collector outputs are required in a through-hole format. It serves as a direct replacement for other 74LS05 variants in DIP packages. Consider the 8mA sink current capability for driving loads. Evaluate if the 32ns propagation delay meets timing requirements compared to faster families like 74S or 74ALS.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS series, known for low-power Schottky technology. The 74LS05 specifically provides hex inverters with open-collector outputs, distinguishing it from standard push-pull inverters like the 74LS04. It is widely used in legacy digital systems requiring robust TTL compatibility and flexible output interfacing capabilities.

Inverter Gates Replacement Considerations

SN74LS05D (SOIC package), SN74LS05NSR (Tape & Reel), SN74LS05DE4 (Lead-free variant). Verify package type and moisture sensitivity levels when substituting.
