74LCX32MTR

Inverter Gates Overview

The STMicroelectronics 74LCX32MTR is a low-voltage CMOS quad 2-input OR 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 5.2ns at VCC = 3V and symmetrical output impedance with |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 safe interfacing with 5V signal environments while operating at lower voltages.
• Provides high-speed logic operation with balanced propagation delays suitable for demanding timing 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 between 3.3V logic devices and 5V signal environments
• PCI bus level applications requiring guaranteed drive capability

Inverter Gates Procurement Notes

Verify the specific package type required, as the MTR suffix indicates Tape & Reel packaging in the SO-14 format. Confirm that the 5V input tolerance meets system interface requirements. Ensure ESD handling procedures are followed given the device's sensitivity. Check for any automotive or industrial temperature grade requirements if applicable to the target environment.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR gate is needed with 5V input tolerance and low power consumption. It is suitable for designs requiring compatibility with the standard 74 series pinout but operating at reduced voltages. Consider the 5.2ns max propagation delay for speed-critical paths. Verify that the 24mA output drive capability satisfies load requirements.

Inverter Gates Part Context

The 74LCX32 belongs to STMicroelectronics' 74LCX family of low-voltage CMOS logic devices. This family is designed for high-speed, low-power applications operating between 2.0V and 3.6V. The 74LCX series offers performance comparable to older 5V AC/ACT families but with significantly lower power consumption. It is widely used in portable electronics and systems requiring voltage translation between different logic levels.

Inverter Gates Replacement Considerations

Direct substitutes include other manufacturers' 74LCX32 parts in SO-14 tape and reel packaging. Ensure replacement parts maintain 5V input tolerance and similar propagation delay specifications. Verify pin compatibility with the original 74 series 32 function. Check if alternative packages like TSSOP are acceptable if form factor flexibility exists.
