74LCX32TTR

Inverter Gates Overview

The STMicroelectronics 74LCX32TTR 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 of 24mA minimum at VCC = 3V. It includes power-down protection on inputs and outputs, balanced propagation delays, and ESD immunity exceeding 2000V (HBM).

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing safe interfacing with 5V signal environments.
• Provides high-speed operation with balanced propagation delays and symmetrical output impedance.
• Includes power-down protection on both inputs and outputs.

Inverter Gates Applications

• Interfacing between 3.3V logic circuits and 5V signal environments.
• PCI bus level applications requiring guaranteed drive capability.

Inverter Gates Procurement Notes

Verify the package type matches the required design constraints, as the TTR suffix indicates Tape & Reel packaging in the TSSOP-14 format. Confirm that the operating conditions align with the specified voltage and temperature ranges before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR gate is needed with 5V tolerance and high-speed performance at 3.3V. Ensure the application requires the specific TSSOP-14 form factor and tape-and-reel packaging configuration provided by the TTR suffix.

Inverter Gates Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from STMicroelectronics. It is functionally compatible with the standard 74 series 32 but optimized for lower voltage operation and reduced power consumption while maintaining high speed comparable to 5V AC/ACT families.

Inverter Gates Replacement Considerations

Direct substitutes include other manufacturers' 74LCX32 variants in TSSOP-14 packages. Verify pin compatibility and electrical specifications such as propagation delay and output current capabilities before substitution.
