Nexperia USA Inc. 74LVC14APW,118

Overview

74LVC14APW,118 from Nexperia is a hex inverting Schmitt trigger IC with 5 V tolerant inputs, operating from 1.2 V to 3.6 V supply, delivering hysteresis-based noise immunity for signal conditioning in mixed-voltage digital systems. It features six independent inverters, each with VT+ = 1.2–2.0 V and VT− = 0.8–1.5 V (at VCC = 3.6 V), 6.4 ns typical propagation delay at 3.3 V, and ±24 mA output drive capability.

For engineers reviewing the 74LVC14APW,118 datasheet, 74LVC14APW,118 pinout, 74LVC14APW,118 application, or 74LVC14APW,118 equivalent, this device is selected for robust waveform shaping, clockless oscillator design, and level translation between 3.3 V logic and legacy 5 V interfaces - especially where input noise rejection and rail-to-rail compatibility are critical.

Technical Context

The 74LVC14APW implements six independent CMOS Schmitt-trigger inverters with asymmetric hysteresis (VH = 0.3–1.2 V) to reject noise on slow or noisy input edges. Each channel accepts inputs up to 5.5 V regardless of VCC (1.2–3.6 V), enabling bidirectional voltage translation without external components.

Its dynamic behavior is characterized by input-dependent propagation delay (1.0–12.7 ns across VCC range), low output skew (<1.5 ns), and power dissipation capacitance CPD = 15.6 pF at 3.3 V - supporting stable operation in high-noise industrial timing and relaxation oscillator circuits.

FAQ

Can 74LVC14APW,118 operate with a 1.2 V supply?

Yes - the device is fully specified down to 1.2 V supply voltage per JEDEC JESD8-C/JESD36 standards. At 1.2 V, propagation delay increases to 16 ns, input thresholds scale proportionally (VT+ ≈ 0.2–1.0 V), and output drive reduces to ±4 mA, but all six channels remain functional and noise-immune.

Is the exposed thermal pad on SOT402-1 (TSSOP14) electrically connected?

No - the exposed pad on the 74LVC14APW,118 TSSOP14 package (SOT402-1) is not electrically connected to any internal node. Per Nexperia documentation, it may be left floating or tied to GND for thermal enhancement, but soldering it to ground imposes no electrical requirement or risk.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are characterized up to 50 pF load capacitance at VCC = 3.0 V with tpd ≤ 8.0 ns and skew ≤ 1.5 ns. Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for >100 pF loads, add series termination or buffer stages to maintain signal integrity.

Does 74LVC14APW,118 support hot-swap or live-insertion?

No - the device lacks powered-off protection or Ioff (input/output disable during power-down) functionality. Applying input signals while VCC = 0 V violates absolute maximum ratings (VI = −0.5 V min), risking latch-up or permanent damage; always power VCC before asserting inputs.
