The SN74LVC1G14-EP is a single-gate Schmitt-trigger inverter: it inverts its input (Y = NOT A), but unlike an ordinary inverter it has a true Schmitt-trigger input with separate positive-going (V_T+) and negative-going (V_T−) thresholds. That hysteresis — roughly 0.56 V wide at 3.3 V — means a slow, noisy or ringing signal still produces exactly one clean, fast output edge instead of multiple glitches.

That makes it the standard tool for signal conditioning: squaring up the output of an RC delay, cleaning a slow sensor or switch edge, restoring a degraded clock, or providing noise immunity at the input of a logic chain. Because it is a single gate in SOT-23, it does that job exactly where the noisy signal enters the board.

This order option is the “-EP” Enhanced Product: a controlled baseline (one fab, one assembly/test site), DMS support, change notification and an extended −55 °C to +125 °C grade. Electrically it is a full LVC gate — 1.65 V–5.5 V, 5.5 V-tolerant inputs, ±24 mA drive, I_off partial-power-down — for harsh, long-life equipment that must keep cleaning its signals over temperature.

Note: Values are from the Texas Instruments SN74LVC1G14-EP data sheet (SCES674). Confirm every parameter, especially the temperature-dependent thresholds and timing, against the latest data sheet before committing a design.

The SN74LVC1G14-EP in this order option (MDBVREP) ships in the DBV 5-pin SOT-23 (JEDEC MO-178, 1.45 mm maximum height, body about 2.9 mm × 1.6 mm). The robust SOT-23 outline suits the harsh-environment boards the EP grade targets, where leads are easier to inspect and rework than a leadless package. Supplied tape-and-reel.

The dimensioned drawing below gives the SOT-23-5 body and lead geometry for the land pattern and assembly stencil.

The single inverter maps onto five pins (top view):

• Pin 1 – NC: No internal connection; leave open or tie to a plane for support.
• Pin 2 – A (Input): Schmitt-trigger logic input; 5.5 V-tolerant; accepts slow/noisy edges.
• Pin 3 – GND: Ground (0 V) reference.
• Pin 4 – Y (Output): Inverted output, Y = NOT A; drives ±24 mA at 3.3 V.
• Pin 5 – V_CC: Supply, 1.65 V to 5.5 V; decouple with a local 0.1 µF capacitor.

The closest relatives are other single Schmitt-trigger gates. The SN74LVC1G17 is the non-inverting Schmitt-trigger (Y = A) counterpart; use it when you need clean-up without inversion. Confirm inverting vs non-inverting and the temperature grade before substituting.

Logic Family Comparison

Texas Instruments (TI, NASDAQ: TXN), of Dallas, Texas, is a leading logic supplier; its LVC Schmitt-trigger single gates (inverting '14 and non-inverting '17) are standard tools for signal conditioning, and the Enhanced-Product (EP) variants add an extended-temperature, controlled-baseline pedigree for long-life programmes.

The governing document is the SN74LVC1G14-EP data sheet (SCES674), which defines the Schmitt thresholds, the I_off behaviour, the M-temperature timing and the DBV package. InFortune Electronics supplies the device under code 1P1G14MDBVREP and provides sourcing and technical support.
