SN74ALS05ADG4

Overview

The SN74ALS05ADG4 is a hex inverter manufactured by Texas Instruments, featuring open-collector outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports a low-level output current of 8mA. The device exhibits a propagation delay of approximately 54ns and functions reliably across an operating temperature range of 0°C to +70°C. Packaged in a 14-pin SOIC format, it serves as a standard logic component for digital signal inversion applications requiring high drive capability.

Feature Summary

• Provides six independent inverting channels with open-collector output configuration
• Capable of sourcing significant low-level output current for direct interface driving
• Compatible with standard TTL input logic levels

Applications

• Digital signal inversion in microprocessor systems
• Driving relays or lamps via open-collector interface
• Level shifting between different logic families

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm package type and environmental compliance status. Ensure the required operating temperature range aligns with your system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when six inverted signals with open-collector outputs are required. It is suitable for applications needing higher current sinking capability than standard CMOS inverters provide. Consider the SOIC package size and thermal characteristics during PCB layout planning.

Part Context

This part belongs to the SN74ALS series, representing Advanced Low-power Schottky logic technology. It offers improved speed and power consumption characteristics compared to earlier LS series devices while maintaining pin compatibility with standard 74-series logic families.

Replacement Considerations

Direct substitutes include SN74ALS05AD and SN74ALS05ADE4. Verify functional equivalence and package dimensions before substitution.
