MC74LCX14DG

Inverter Gates Overview

The MC74LCX14DG is a low voltage CMOS hex Schmitt inverter 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 capabilities of 24 mA each. It exhibits near-zero static supply current, typically 10 µA, which substantially reduces system power requirements. The component is housed in a 14-lead SOIC package.

Inverter Gates Feature Summary

• Features Schmitt-trigger inputs that square up slow input signals and provide maximum noise immunity.
• Offers 5.0 V tolerant inputs for direct interface capability with 5.0 V TTL logic without level shifting.
• Provides high impedance TTL compatible inputs to significantly reduce current loading on input drivers.
• Delivers balanced 24 mA output drive capability for both sourcing and sinking currents.

Inverter Gates Applications

• Line receiver applications for receiving slow input signals
• Interface between 5.0 V TTL logic and low voltage CMOS circuits
• Signal conditioning where noise immunity is required

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DG' corresponds to the SOIC-14 package style as defined in the manufacturer's ordering information. Confirm RoHS compliance status and lead-free packaging details directly from the latest datasheet revision or official distributor documentation prior to procurement.

Inverter Gates Selection Notes

Select this component when a hex inverter with hysteresis is required for noisy environments or slow signal edges. Ensure the operating voltage falls within the 1.65 V to 5.5 V range. Consider the 5.0 V input tolerance if interfacing with higher voltage logic families. Verify thermal dissipation requirements if driving heavy loads at maximum current ratings.

Inverter Gates Part Context

This part belongs to the LCX logic family, designed for low voltage operation. It shares pin configuration and function compatibility with the standard MC74LCX04, but incorporates Schmitt trigger functionality on all inputs. The series is optimized for battery-powered applications due to its low quiescent current characteristics.

Inverter Gates Replacement Considerations

MC74LCX04DG: Pin-compatible alternative lacking Schmitt trigger inputs. MC74ACT14DG: Higher voltage operation (5V only) with Schmitt triggers. MC74LVC14: Different voltage range and electrical characteristics.
