MM74HCT32MTC

Inverter Gates Overview

The MM74HCT32MTC is a quad 2-input OR gate manufactured by Fairchild Semiconductor. It belongs to the HCT logic series, designed for high-speed CMOS operation with performance comparable to LSTTL while maintaining low power consumption. The device features buffered outputs for high noise immunity and stable output characteristics. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. The component is housed in a 14-SOIC surface-mount package.

Inverter Gates Feature Summary

• High-speed CMOS technology providing LSTTL-compatible performance
• Buffered outputs ensuring high noise immunity and stability
• Input protection circuits against static discharge and transient excess voltage

Inverter Gates Applications

• Direct interfacing between HSC2MOS systems and TTL components
• Plug-in replacements for LSTTL devices to reduce power consumption
• General digital logic circuit design requiring OR functionality

Inverter Gates Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor has undergone corporate restructuring and brand transitions. Confirm that the specific part number corresponds to the intended generation of production. Ensure compatibility with existing system requirements regarding voltage levels and signal integrity before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when LSTTL pinout compatibility is required alongside CMOS power efficiency. The HCT series ensures direct interface capability with standard TTL logic families. Consider the 14-SOIC package dimensions for PCB layout constraints. Verify that the 4.5V to 5.5V supply range aligns with the target system's power distribution network.

Inverter Gates Part Context

This component is part of the broader 74HCT logic family, which bridges the gap between high-speed CMOS and Low-power Schottky TTL technologies. The 'MTC' suffix typically denotes the 14-SOIC surface-mount package variant. It serves as a functional equivalent to other quad 2-input OR gates within the industry-standard 74xx series nomenclature.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include M74HCT32 from STMicroelectronics. Other equivalents within the same logic family may be considered if pin compatibility and electrical specifications match exactly.
