MC74LCX00MELG

Inverter Gates Overview

The MC74LCX00MELG is a quad 2-input NAND gate integrated circuit manufactured by onsemi. It belongs to the LCX logic series and operates within a supply voltage range of 2 V to 3.6 V. The device features four independent gates, each with two inputs, housed in a 14-pin SOEIAJ surface-mount package. Key electrical specifications include a propagation delay of 5.5 ns at 3.3 V with 50 pF load, and output drive currents of ±24 mA. The component supports a wide operating temperature range from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Provides four independent 2-input NAND logic functions in a single compact package
• Operates with low supply voltages ranging from 2 V to 3.6 V for power efficiency
• Delivers strong output drive capability with ±24 mA current sourcing and sinking
• Ensures high-speed signal processing with a propagation delay of 5.5 ns

Inverter Gates Applications

• Portable battery-powered electronic devices requiring low voltage operation
• Consumer electronics utilizing CMOS logic interfaces
• Industrial control systems needing reliable NAND logic functions
• Communication equipment interfacing between different logic families

Inverter Gates Procurement Notes

Verify the specific suffix 'MELG' corresponds to the SOEIAJ-14 tape-and-reel packaging configuration. Confirm RoHS compliance status and manufacturing origin details through official onsemi documentation or authorized distributor declarations prior to procurement. Ensure the supplier provides valid traceability records for quality assurance purposes.

Inverter Gates Selection Notes

Select this component when a quad NAND gate is required for low-voltage (2V–3.6V) applications. The SOEIAJ-14 package is suitable for space-constrained surface-mount designs. Consider the ±24 mA drive strength for direct interface with compatible loads without additional buffering. Verify that the 5.5 ns propagation delay meets the timing requirements of the target circuit design.

Inverter Gates Part Context

This part is part of the onsemi 74LCX00 family, which offers high-speed CMOS performance with low power consumption. The LCX series is designed to bridge the gap between older 74HC and newer 74LVC technologies, providing compatibility with both 3.3 V and 5 V systems while maintaining low static power dissipation. The MELG suffix specifically denotes the reel-packaged variant of the SOEIAJ-14 footprint.
