74LCX08TTR

Inverter Gates Overview

The STMicroelectronics 74LCX08TTR is a low voltage CMOS quad 2-input AND 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 capable of interfacing with 5V signal environments. The device provides high-speed performance with a maximum propagation delay of 4.1ns at VCC = 3V and symmetrical output impedance ensuring |IOH| = IOL = 24mA (min) at VCC = 3V. It includes power-down protection on inputs and outputs, balanced propagation delays, and latch-up performance exceeding 500mA.

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 and symmetrical output impedance for reliable signal transmission.
• Incorporates power-down protection on both inputs and outputs to prevent excessive current draw during power-off states.

Inverter Gates Applications

• Low power and high speed 3.3V digital applications
• Interfacing between 3.3V systems and 5V signal environments
• PCI bus level compatible designs

Inverter Gates Procurement Notes

Verify the specific package type and tape-and-reel quantity requirements against your manufacturing needs. Confirm that the 5V tolerant input specifications align with your system's voltage levels. Ensure compliance with RoHS directives if applicable to your region. Check for any automotive or industrial qualification requirements beyond standard commercial grades.

Inverter Gates Selection Notes

Select this component when designing circuits requiring 3.3V operation with 5V input compatibility. Consider its high-speed characteristics for applications demanding fast switching times. Evaluate the power consumption benefits compared to older AC/ACT families. Ensure the TSSOP-14 package fits your PCB layout constraints.

Inverter Gates Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from STMicroelectronics. It implements the standard 7408 quad 2-input AND gate function but optimized for modern low-voltage digital systems. The TTR suffix indicates it is supplied in a tape and reel format suitable for automated surface-mount assembly processes.

Inverter Gates Replacement Considerations

Direct pin-compatible alternatives include other manufacturers' 74LCX08 variants. Verify electrical parameters such as propagation delay and output drive strength match your design requirements before substitution.
