MC74VHC14DG

Inverter Gates Overview

The MC74VHC14DG is a Hex Schmitt Inverter manufactured by onsemi using silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and features six independent inverters in a 14-lead SOIC package. The device provides high-speed operation with typical propagation delays of 5.5 ns at 5.0 V, low power dissipation with maximum quiescent current of 2 µA, and balanced propagation delays. It includes power-down protection on inputs and offers high noise immunity with hysteresis voltages up to 1.6 V.

Inverter Gates Feature Summary

• Schmitt trigger inputs provide hysteresis for squaring up slow signals and maximizing noise immunity
• Power-down protection prevents device destruction caused by supply voltage mismatches
• Outputs tolerate voltages up to 5.5 V allowing interface between 5 V and 3 V systems

Inverter Gates Applications

• Line receiver for slow input signals
• Level converter for interfacing 3.3 V to 5.0 V systems
• Buffer output providing high noise immunity and stable output

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DG' corresponds to the SOIC-14 tube packaging configuration as defined in the manufacturer's ordering information. Confirm RoHS compliance status and lead-free marking requirements against the latest datasheet revision before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when hex Schmitt trigger functionality is required alongside standard CMOS logic compatibility. Ensure the application utilizes the full 5.0 V CMOS level output swings necessary for effective level conversion between different voltage domains while maintaining low power consumption characteristics.
