74LCX00MTR

Inverter Gates Overview

The STMicroelectronics 74LCX00MTR 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 inputs tolerant up to 5.5V 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 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 per JESD 17.

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing direct interface between 5V systems and 3.3V logic levels.
• Provides high-speed operation with balanced propagation delays suitable for demanding digital applications.
• Includes power-down protection circuits 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 specific package type required for the application, as the 74LCX00MTR designation corresponds to the SOP-14 tape and reel configuration. Confirm that the operating temperature range of -55°C to 125°C meets the environmental requirements. Ensure input voltages do not exceed the absolute maximum ratings to prevent damage. Check for pin compatibility with existing 74 series 00 designs if migrating from older technologies.

Inverter Gates Selection Notes

Select this component when a quad 2-input NAND function is needed in a low-voltage environment. It is suitable for designs requiring 5V tolerance on inputs while operating at 3.3V. Consider the symmetrical output impedance and high drive capability of 24mA for driving loads directly. Verify that the propagation delay specifications meet the timing constraints of the system.

Inverter Gates Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic devices. It is functionally and pin-compatible with the standard 74 series 00 but offers improved speed and lower power consumption. The technology utilizes advanced sub-micron processes to achieve performance comparable to 5V AC/ACT families while maintaining low power dissipation characteristics typical of modern CMOS logic.

Inverter Gates Replacement Considerations

Direct substitutes include other manufacturers' 74LCX00 variants in SOP-14 or TSSOP-14 packages. Verify that any replacement maintains the same 5V tolerant input specifications and operating voltage range. Ensure the alternative device meets the required ESD protection levels and latch-up performance standards.
