Nexperia USA Inc. 74LV14PW,112

Overview

74LV14PW,112 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with 14-pin TSSOP package, operating from 1.0 V to 5.5 V supply, delivering six independent hysteresis-input inverters for noise-immune signal conditioning. It transforms slow-rising/falling inputs into clean digital outputs and supports TTL-level inputs at VCC = 2.7–3.6 V, widely used in waveform shaping and relaxation oscillator circuits.

For engineers reviewing the 74LV14PW,112 datasheet, 74LV14PW,112 pinout, 74LV14PW,112 application, or 74LV14PW,112 equivalent, key selection criteria include input hysteresis voltage (VH), propagation delay (13 ns typical at 3.3 V), supply voltage range (1.0–5.5 V), operating temperature (−40 °C to +125 °C), and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The 74LV14PW,112 implements six independent Schmitt-trigger inverter stages, each with asymmetric input thresholds (VT+ and VT−) defining hysteresis-e.g., 1.60 V/1.05 V typical at VCC = 3.0 V. Its CMOS architecture ensures low static current (≤40 μA at 5.5 V) and TTL-compatible input levels within specified VCC ranges.

Dynamic behavior is characterized by propagation delays of 13 ns (typical, CL = 15 pF, VCC = 3.3 V), power dissipation capacitance of 15 pF, and output drive capability of ±12 mA. Input clamping current is rated ±20 mA, and total power dissipation is 500 mW with thermal derating above 81 °C for the TSSOP14 package.

FAQ

What is the minimum supply voltage at which 74LV14PW,112 guarantees functional operation?

The 74LV14PW,112 is guaranteed to function down to VCC = 1.0 V, with static characteristics fully specified from 1.2 V. At 1.0 V, inputs must be driven to GND or VCC (not intermediate levels), and timing parameters are not guaranteed-but basic inversion remains operational per Nexperia's characterization.

Can the exposed thermal pad on the TSSOP14 package be soldered, and if so, how should it be connected?

Yes, the exposed pad on SOT402-1 may be soldered, but it has no electrical function. Per Nexperia's datasheet, it should remain electrically floating or be connected to VCC-never to GND-to avoid unintended coupling paths or thermal stress mismatches during reflow.

How does the input hysteresis voltage (VH) vary with supply voltage, and what is its practical impact?

VH increases with VCC: 0.3 V typical at 1.2 V, 0.65 V at 3.0 V, and 1.0 V at 5.5 V. This scaling ensures consistent noise rejection margin relative to signal swing-e.g., at 3.3 V, VH ≈ 20% of rail, enabling reliable operation even with 300 mV of coupled noise on sensor lines.

Is 74LV14PW,112 qualified for automotive applications per AEC-Q100?

No. The 74LV14PW,112 is not AEC-Q100 qualified. Nexperia explicitly states in its legal disclaimers that unless expressly marked "automotive qualified," products are unsuitable for automotive use. For automotive designs, consult Nexperia's dedicated automotive-grade variants such as the 74LV14-Q100 series.
