Product Overview
The SN74LVC1G14 is a Texas Instruments single Schmitt-trigger inverter in the Signal_Chain category. Its positive-logic function is Y = NOT A, using a Schmitt-trigger input stage with specified positive-going and negative-going input thresholds plus hysteresis across supply voltages from 1.65 V to 5.5 V.
Recommended operating conditions specify a 1.65 V to 5.5 V supply range, 1.5 V data-retention supply voltage, 0 V to 5.5 V input range, and 0 V to VCC output range. Output drive ratings are specified up to -32 mA high-level current and 32 mA low-level current at the listed VCC conditions, with leakage, supply current, input capacitance, and propagation delay characterized in the datasheet facts.
Assembly options include DBV SOT-23-5, DCK SC70-5, DRL SOT-5X3-5, DRY USON-6, DSF X2SON-6, YZP DSBGA-5, YZV DSBGA-4, and DPW X2SON-5 packages. Applications should align with single-gate inversion, Schmitt-trigger input conditioning, low-voltage logic interfacing, and partial-power-down signal paths using Ioff circuitry.

Procurement Notes
When requesting a quote for SN74LVC1G14, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What logic function does the SN74LVC1G14 provide?
The SN74LVC1G14 provides a positive-logic inverter function, specified as Y = NOT A. The input uses a Schmitt-trigger structure, with positive-going and negative-going threshold voltages characterized across the listed supply voltages.
What supply range is specified for normal operation?
The recommended operating supply range is 1.65 V to 5.5 V. The extracted facts also specify a 1.5 V supply condition for data retention only, separate from the normal recommended operating range.
Which package options are listed for this device?
The listed packages include DBV SOT-23-5, DCK SC70-5, DRL SOT-5X3-5, DRY USON-6, DSF X2SON-6, YZP DSBGA-5, YZV DSBGA-4, and DPW X2SON-5 body sizes.
Does the SN74LVC1G14 support partial-power-down operation?
Yes. The extracted facts state that Ioff circuitry disables outputs when the device is powered down, preventing current backflow into the device under the specified partial-power-down support condition.
