74LCX08MTR

Inverter Gates Overview

The STMicroelectronics 74LCX08MTR is a low-voltage CMOS quad 2-input AND gate manufactured using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2.0V to 3.6V, with data retention down to 1.5V. The device features 5V tolerant inputs capable of interfacing with 5V signal environments while maintaining high-speed performance comparable to the 5V AC/ACT family at lower power consumption. Propagation delay is guaranteed at a maximum of 4.1ns at VCC = 3.0V. Outputs provide symmetrical impedance with minimum drive currents of ±24mA at VCC = 3.0V to 3.6V. The component includes power-down protection on inputs and outputs, balanced propagation delays (tPLH ≈ tPHL), and latch-up performance exceeding 500mA per JESD 17.

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing direct interfacing between 3.3V logic systems and 5V signal environments without level shifting components.
• Provides high-speed operation with balanced propagation delays and symmetrical output impedance for reliable signal integrity in digital circuits.
• Incorporates power-down protection on both inputs and outputs to prevent excessive current draw during power-off states.
• Delivers robust ESD immunity and transient excess voltage protection across all input and output pins.

Inverter Gates Applications

• Low-power and high-speed 3.3V digital logic applications
• Interfacing 3.3V logic devices with 5V signal environments
• PCI bus level compatible logic circuits

Inverter Gates Procurement Notes

Verify the specific package type required for your design, as the base part number 74LCX08 covers multiple packages including SOP-14 and TSSOP-14. Confirm that the MTR suffix corresponds to the tape and reel packaging format suitable for automated surface-mount assembly processes. Ensure compatibility with your board's thermal management requirements given the operating temperature range specifications.

Inverter Gates Selection Notes

Select this component when designing low-voltage digital systems requiring fast switching speeds and minimal power dissipation. It is suitable for replacing older 74LS or 74HC series parts where lower voltage operation and higher speed are needed. Consider its 5V tolerance feature if the system involves mixed-voltage signaling. Verify that the SOIC-14 or TSSOP-14 footprint matches your PCB layout constraints.

Inverter Gates Part Context

This device belongs to the 74LCX logic family, which represents low-voltage CMOS technology designed for high-speed, low-power applications. It maintains pin and function compatibility with standard 74 series 08 devices, facilitating drop-in replacements in existing designs. The LCX series is optimized for 3.3V operation while offering performance metrics similar to faster but more power-hungry families like AC or ACT.

Inverter Gates Replacement Considerations

Check datasheets for alternative manufacturers' equivalents such as MC74LCX08 or SN74LCX08 to ensure identical electrical characteristics and pinout compatibility before substitution.
