74LCX00TTR

Inverter Gates Overview

The STMicroelectronics 74LCX00TTR is a low-voltage CMOS quad 2-input NAND 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 4.3ns 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 latch-up performance exceeding 500mA per JESD 17.

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing direct interface between 5V systems and 3V logic levels.
• Provides high-speed 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.

Inverter Gates Applications

• Low-power and high-speed 3.3V logic applications
• Interfacing 5V signal environments to 3V systems
• PCI bus level applications requiring guaranteed drive currents

Inverter Gates Procurement Notes

Verify the package type matches the required footprint, as the TTR suffix indicates tape and reel packaging in TSSOP-14. Confirm that the operating temperature range and voltage specifications align with the target system requirements before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when 5V tolerance is required for inputs while maintaining low-voltage CMOS performance. It serves as a drop-in replacement for standard 74 series 00 devices due to pin and function compatibility, offering improved speed and lower power consumption compared to older AC/ACT families.

Inverter Gates Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic gates manufactured by STMicroelectronics. The LCX series is designed to bridge the gap between traditional 5V logic and modern low-voltage systems, providing robust ESD protection and high noise immunity suitable for various consumer and industrial electronic designs.

Inverter Gates Replacement Considerations

Pin and function compatible with 74 series 00 devices. Can replace other 74LCX00 variants from different manufacturers if package and electrical specifications match.
