SN74LS09D

Inverter Gates Overview

The SN74LS09D is a quad two-input AND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic family and features open-collector outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum propagation delay of 35ns at 5V with a 15pF load. It provides an output current capability of 8mA and functions reliably across a temperature range of 0°C to 70°C.

Inverter Gates Feature Summary

• Contains four independent two-input AND gates for complex logic implementation
• Features open-collector outputs suitable for wired-AND configurations
• Compatible with standard TTL logic families

Inverter Gates Applications

• Digital logic circuits requiring AND operations
• Wired-AND bus structures
• Interface logic between different voltage domains using pull-up resistors

Inverter Gates Procurement Notes

Verify the package type matches the required footprint, as the 'D' suffix indicates a SOIC package. Confirm the manufacturer source is authorized to ensure component authenticity. Check RoHS compliance status if environmental regulations apply to the specific production batch. Ensure the operating temperature range meets the system requirements.

Inverter Gates Selection Notes

Select this component when open-collector AND functionality is required in a standard TTL environment. The open-collector design allows for level shifting or driving loads higher than the logic supply voltage via external pull-up resistors. Consider the 8mA sink current capability when designing the output stage. Verify that the 35ns propagation delay fits the timing constraints of the application.

Inverter Gates Part Context

This part is part of the SN54/74LS09 series, which includes variants like SN74LS09DR (tape and reel) and SN74LS09N (DIP). The SN74LS09D specifically denotes the surface-mount SOIC version. It shares functional compatibility with other 74LS series logic gates but is distinct from CMOS equivalents like the 74HC09 due to different power and speed characteristics.

Inverter Gates Replacement Considerations

SN74LS09DR is a direct equivalent in tape-and-reel packaging. SN74LS09N offers the same function in a DIP package. Cross-vendor equivalents such as MC74LS09 are functionally compatible.
