MC74LCX32DTR2

Inverter Gates Overview

The MC74LCX32DTR2 is a low-voltage CMOS quad 2-input OR gate manufactured by onsemi. It operates from a supply voltage range of 1.65 V to 5.5 V and features 5.0 V tolerant inputs, allowing safe interfacing with 5.0 V devices. The device provides balanced output sink and source capability of 24 mA at 3.0 V. Propagation delay ranges from 9.8 ns at 1.65–1.95 V to 4.0 ns at 4.5–5.5 V. It is housed in a TSSOP-14 package.

Inverter Gates Feature Summary

• Features 5.0 V tolerant inputs for direct interface with 5.0 V TTL logic
• Provides high impedance inputs to reduce current loading on drivers
• Delivers balanced output sink and source capability of 24 mA at 3.0 V
• Operates with near zero static supply current to reduce system power requirements

Inverter Gates Applications

• Interface between 5.0 V TTL logic and low-voltage CMOS systems
• General purpose digital logic applications requiring wide supply voltage operation
• Portable and battery-powered equipment due to low quiescent current

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the TSSOP-14 tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the 'G' suffix in standard ordering information versus the base model number provided. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR function is required with mixed voltage domain compatibility. The wide supply range supports both 1.8 V and 3.3 V/5.0 V systems. Consider the TSSOP-14 package constraints for PCB layout. Verify input leakage and propagation delay specifications against the target switching frequency requirements.

Inverter Gates Part Context

This part belongs to the LCX series of low-voltage CMOS logic gates. The LCX family is designed for high performance while maintaining compatibility with standard logic levels. It serves as a bridge between older 5 V logic standards and modern low voltage digital circuits.
