SN74LVC1G14DCKR

Inverter Gates Overview

The SN74LVC1G14DCKR is a single Schmitt-trigger inverter from Texas Instruments, designed for operation within a 1.65 V to 5.5 V supply voltage range. It performs the Boolean function Y=A and features distinct input threshold levels for positive (VT+) and negative (VT-) transitions, providing noise immunity. The device supports Ioff circuitry to disable outputs during partial power-down, preventing backflow current damage. It operates across a temperature range of -40°C to +125°C, with a maximum static current of 10 µA and output drive capabilities of ±32 mA at 3.3 V.

Inverter Gates Feature Summary

• Schmitt-trigger action provides distinct input thresholds for rising and falling signals to filter noise
• Ioff circuitry disables outputs to prevent damaging backflow current during partial power-down
• Supports 5.5 V input tolerance while operating on lower supply voltages
• Green RoHS-compliant construction without antimony or bromine

Inverter Gates Applications

• Signal processing and conditioning
• Portable equipment
• Consumer electronics
• Computer and computer peripherals
• Power management systems

Inverter Gates Procurement Notes

Verify the specific package marking and manufacturer date code against the official datasheet to ensure authenticity. Confirm that the ordering suffix matches the required tape-and-reel configuration. Check for any recent product change notices regarding lead material or packaging updates. Ensure the component meets the required environmental specifications for your application.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger input structure. It is suitable for interfaces requiring level shifting between different voltage domains. Consider the SC-70-5 package size for space-constrained designs. Verify that the propagation delay characteristics meet the timing requirements of the target digital system.
