SN74LS05N

Inverter Gates Overview

The SN74LS05N is a hex inverter manufactured by Texas Instruments, utilizing Low Power Schottky (LS) logic technology. It features six independent inverters with open-collector outputs housed in a standard plastic DIP-14 package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. Electrical characteristics include a low-level output current capability of up to 8 mA at VCC = 4.75 V. Switching performance under typical conditions (VCC = 5 V, RL = 2 kΩ, CL = 15 pF) specifies propagation delays ranging from 15 ns to 32 ns.

Inverter Gates Feature Summary

• Contains six independent inverters with open-collector outputs requiring external pull-up resistors for proper operation.
• Capable of implementing active-low wired-OR or active-high wire-AND functions when connected to other open-collector outputs.
• Suitable for generating high VOH levels through the use of open-collector architecture.

Inverter Gates Applications

• Signal inversion in digital logic circuits
• Implementation of wired-OR or wire-AND logic configurations
• Generation of higher output voltage levels

Inverter Gates Procurement Notes

Verify that the component matches the specific SN74LS05N designation, as ordering suffixes indicate distinct packaging formats such as tubes or tape-and-reel. Confirm the manufacturer origin, typically Texas Instruments for this part number, and ensure the package type aligns with design requirements. Check for RoHS compliance status and verify the operating temperature range corresponds to the intended application environment before finalizing procurement.

Inverter Gates Selection Notes

Select the SN74LS05N when a hex inverter with open-collector outputs is required for interfacing with different logic families or loads. Ensure the circuit design includes appropriate pull-up resistors to define the high logic state. Consider the LS series speed and power consumption trade-offs compared to standard or advanced variants. Verify that the 8 mA sink current capability meets the load requirements of the driven components.

Inverter Gates Part Context

This component belongs to the 7400 series of logic integrated circuits, specifically the Low Power Schottky (LS) family known for balanced speed and power dissipation. The '05' designation identifies it as a hex inverter with open-collector outputs. It is functionally compatible with other manufacturers' 74LS05 parts, facilitating cross-brand sourcing while maintaining pinout and electrical standardization across the industry.

Inverter Gates Replacement Considerations

Direct functional substitutes include SN74S05N and SN7405N, though these belong to different logic families with varying electrical characteristics. Cross-manufacturer equivalents such as ON Semiconductor MC74LS05N are available. Verify that any replacement maintains the open-collector output configuration and DIP-14 package compatibility.
