74LCX02MTR

Inverter Gates Overview

The STMicroelectronics 74LCX02MTR is a low-voltage CMOS quad 2-input NOR gate fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2.0V to 3.6V, featuring 5V tolerant inputs for interfacing with 5V signal environments. The device provides high-speed performance with a maximum propagation delay of 4.4ns at VCC = 3V and symmetrical output impedance of 24mA minimum at VCC = 3V. It includes power-down protection on inputs and outputs, balanced propagation delays, and ESD immunity exceeding 2000V HBM.

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing direct interfacing with 5V signal environments while operating at lower voltages.
• Provides high-speed logic operation with balanced propagation delays suitable for demanding digital applications.
• Includes power-down protection on both inputs and outputs to prevent excessive current draw during power-off states.
• Offers robust ESD protection with immunity exceeding 2000V under Human Body Model testing conditions.

Inverter Gates Applications

• Low-power and high-speed 3.3V digital logic circuits
• Interfacing between 3.3V logic devices and 5V signal environments
• PCI bus level applications requiring guaranteed drive capabilities

Inverter Gates Procurement Notes

Verify the specific package type and tape-and-reel configuration against project requirements before ordering. Confirm that the 74LCX02MTR designation corresponds to the SO-14 package variant as specified in the manufacturer's documentation. Ensure compatibility with existing PCB footprints and assembly processes for surface-mount components.

Inverter Gates Selection Notes

Select this component when designing systems requiring quad 2-input NOR functionality with mixed-voltage interface capabilities. Consider its low power consumption and high speed relative to standard 5V AC/ACT families. Evaluate the 5V input tolerance feature if the design involves signals from higher voltage domains without additional level shifting circuitry.

Inverter Gates Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic integrated circuits manufactured by STMicroelectronics. The LCX family is designed to offer performance comparable to older 5V technologies while consuming significantly less power. It maintains pin and function compatibility with the standard 74 series 02, facilitating straightforward upgrades or replacements in legacy designs.

Inverter Gates Replacement Considerations

Direct substitutes include other manufacturers' 74LCX02 variants in SO-14 packages. Verify electrical characteristics such as propagation delay and output drive current to ensure functional equivalence. Check for any differences in recommended operating conditions or absolute maximum ratings that might affect system reliability.
