Product Overview
The SN74LVC3G14 is a Texas Instruments triple Schmitt-trigger inverter. Each of its three independent inverter channels implements Y = NOT A, with the function table specifying Y = L when A = H and Y = H when A = L. The Schmitt-trigger input structure is defined by positive-going and negative-going input thresholds plus input hysteresis across VCC values from 1.65 V to 5.5 V.
Recommended operation covers 1.65 to 5.5 V VCC, 0 to 5.5 V input voltage, 0 to VCC output voltage, and -40 to 125 °C free-air temperature. The device supports data retention at 1.5 V and includes an Ioff feature that disables outputs during power-down conditions to prevent damaging current backflow during live insertion or back-drive conditions.
Package options include SSOP (DCT), VSSOP (DCU), and DSBGA (YZP), all with 8 pins.

Procurement Notes
When requesting a quote for SN74LVC3G14, 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 MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
FAQ
What logic function does SN74LVC3G14 provide?
SN74LVC3G14 provides three independent Schmitt-trigger inverter channels. For each inverter, the logic function is Y = NOT A, with the function table showing Y = L when A = H and Y = H when A = L.
What supply voltage range is recommended for this device?
The recommended operating VCC range is 1.65 to 5.5 V. The extracted facts also list 1.5 V for data-retention-only operation and a recommended input voltage range of 0 to 5.5 V.
Which package options are listed for SN74LVC3G14?
The listed 8-pin package options are SSOP (DCT), VSSOP (DCU), and DSBGA (YZP). Tape-and-reel orderable variants are documented in the package option addendum.
Does SN74LVC3G14 support partial-power-down operation?
Yes. The Ioff feature disables outputs to prevent damaging current backflow when powered down, during live insertion, or under back-drive protection conditions.
What ESD protection levels does SN74LVC3G14 offer?
The device provides 2000 V HBM, 200 V MM, and 1000 V CDM ESD protection per JESD22 standards, suitable for robust industrial and automotive environments.
