MM74HCT05M

Inverter Gates Overview

The MM74HCT05M is a hex inverter integrated circuit manufactured by onsemi, belonging to the 74HCT logic family. It features six independent inverters housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 30ns at 5V, with output currents rated at 4.8mA for both high and low states. The inputs are compatible with CMOS levels while providing LSTTL-compatible outputs.

Inverter Gates Feature Summary

• Provides six independent inverting channels for signal inversion applications
• Features open-drain outputs suitable for wired-OR configurations and level shifting
• Ensures compatibility with TTL-driven systems through HCT input thresholds
• Utilizes standard SOIC surface-mount packaging for automated assembly

Inverter Gates Applications

• Digital signal inversion in microcontroller interface circuits
• Level shifting between different logic voltage domains
• Wired-OR logic implementation in bus systems
• General-purpose digital logic processing in consumer electronics

Inverter Gates Procurement Notes

Verify the specific manufacturer marking and date code against official onsemi documentation to ensure authenticity. Confirm that the open-drain output configuration aligns with your circuit design requirements, as this differs from standard push-pull inverters. Check for any obsolete status notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Inverter Gates Selection Notes

Select this component when six inverted signals are required with open-drain output capability. Ensure the system operates strictly within the 4.5V to 5.5V supply range to maintain specified performance. Verify that the load capacitance does not exceed limits that would degrade the 30ns propagation delay specification. Consider thermal dissipation constraints if multiple inverters are actively switching simultaneously.

Inverter Gates Part Context

This part belongs to the MM74HCT series, which bridges CMOS technology with TTL compatibility. Unlike the MM74HCT04 which uses push-pull outputs, the MM74HCT05 utilizes open-drain outputs, allowing for flexible interfacing with various logic families and voltages. It serves as a fundamental building block in digital logic designs requiring signal inversion and bus sharing capabilities.
