SN74LVC1G14DCKTE4

Inverter Gates Overview

The SN74LVC1G14DCKTE4 is a single Schmitt-trigger inverter from the Texas Instruments 74LVC family, designed for operation with supply voltages ranging from 1.65 V to 5.5 V. It features distinct positive and negative input threshold levels to filter noise on slow input signals. The device supports partial power-down mode via Ioff circuitry, which disables outputs to prevent excessive current flow during power-off states. It operates within a temperature range of -40°C to +125°C and is housed in a SC-70-5 (SOT-353) surface-mount package.

Inverter Gates Feature Summary

• Schmitt-trigger action provides defined input thresholds to eliminate signal ambiguity caused by noise or slow rise/fall times.
• Ioff support enables safe partial power-down operation by automatically disabling outputs when the device is unpowered.
• CMOS construction ensures low static power consumption while maintaining high noise immunity across the full voltage range.

Inverter Gates Applications

• Signal conditioning for noisy digital lines
• Pulse width modulation (PWM) signal shaping
• Oscillator circuits requiring stable switching thresholds

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and environmental standards as per Texas Instruments documentation. Confirm the SC-70-5 package marking and pinout alignment with your PCB footprint design. Ensure the ordering part number matches the exact tape-and-reel or cut-tape quantity requirements for your assembly process.

Inverter Gates Selection Notes

Select this component when input signals exhibit significant noise or have slow transition times that could cause multiple triggering in standard inverters. It is suitable for designs requiring robust noise filtering without additional external components. Consider the SC-70-5 package size constraints and the need for Ioff functionality if the system undergoes partial power cycling.

Inverter Gates Part Context

This device belongs to the 74LVC1G14 series of single Schmitt-trigger inverters. It shares functional characteristics with other members of the LVC family but is distinguished by its single-channel configuration and specific packaging options. The DCKT variant denotes the SC-70-5 package form factor used in compact surface-mount applications.

Inverter Gates FAQ

What is the primary function of the Schmitt trigger in this device?

It converts slowly changing analog-like input signals into clean, sharp digital output transitions by utilizing different threshold voltages for rising and falling edges.

How does the Ioff feature benefit the circuit?

It prevents back-powering of the device by disabling the output drivers when the supply voltage is below the specified minimum, protecting downstream components during partial power-down states.
