MC74LCX32MEL

Inverter Gates Overview

The MC74LCX32MEL is a low-voltage CMOS quad 2-input OR gate manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V, ensuring compatibility with various logic families including TTL and LVCMOS. The device features 5V-tolerant inputs, allowing safe interfacing with 5V devices while powered at lower voltages. It provides balanced output sink and source current capabilities of 24 mA. Packaged in a 14-lead TSSOP (MC74LCX32MEL suffix), it offers high noise immunity and near-zero static supply current, significantly reducing system power requirements.

Inverter Gates Feature Summary

• Quad 2-input OR logic function
• 5V tolerant inputs for mixed-voltage interfacing
• Balanced 24mA output drive capability
• Low power dissipation with near-zero static supply current

Inverter Gates Applications

• Mixed-voltage logic level translation between 3.3V/5V systems
• General-purpose digital signal processing
• Portable battery-operated electronic devices
• Consumer electronics requiring low power consumption

Inverter Gates Procurement Notes

Verify the specific package suffix 'MEL' corresponds to the 14-lead TSSOP configuration when ordering. Confirm RoHS compliance status as manufacturing processes may update environmental declarations over time. Ensure the operating temperature range meets your application's thermal requirements, typically spanning -40°C to +85°C for this series. Cross-reference the manufacturer part number directly with official onsemi documentation to avoid counterfeit components.

Inverter Gates Selection Notes

Select the MC74LCX32MEL when a quad 2-input OR gate is required in a compact surface-mount package. Its 5V tolerance makes it suitable for interfaces where input signals may exceed the supply voltage. Consider its 24mA drive strength for moderate load applications. Compare propagation delay specifications against system timing requirements if high-speed operation is critical. Evaluate pinout compatibility with existing PCB footprints designed for standard 14-lead SOIC or TSSOP packages.

Inverter Gates Part Context

This component belongs to the LCX logic family, characterized by low voltage operation and high speed performance. It serves as a successor to older HC/HCT series devices, offering improved power efficiency and voltage flexibility. The MC74LCX32 specifically implements the OR logic function, providing four independent gates in a single package. It is widely used in modern digital circuits requiring reliable logic operations under varying supply conditions.

Inverter Gates Replacement Considerations

Direct substitutes include MC74LCX32DTEL (TSSOP) and MC74LCX32D (SOIC). Verify pinout compatibility before substitution. Check if alternative manufacturers offer equivalent parts with identical electrical characteristics and package dimensions.
