Nexperia USA Inc. XC7WT14DC,125

Overview

XC7WT14DC,125 from Nexperia is a triple inverting Schmitt trigger IC in TSSOP8 (SOT505-2) package, designed for noise-immune signal conditioning with 3 independent buffered channels. It operates from 4.5 V to 5.5 V over -40 °C to +125 °C, delivers ±8 mA output drive, exhibits 0.35–1.6 V hysteresis, and achieves 4.1–9.0 ns propagation delay at 15–50 pF load - used in relaxation oscillators and multivibrator timing circuits.

For engineers reviewing the XC7WT14DC,125 datasheet, XC7WT14DC,125 pinout, XC7WT14DC,125 application, or XC7WT14DC,125 equivalent, key selection criteria include Schmitt trigger hysteresis width (VH), input threshold symmetry (VT+ / VT−), propagation delay consistency across temperature, and ESD robustness (HBM >2000 V, CDM >1000 V) in industrial-grade TSSOP8 packaging.

Technical Context

The XC7WT14DC,125 implements three independent CMOS Schmitt-trigger inverters with symmetrical input thresholds and matched propagation delays. Each channel converts slow-rising/falling analog-like inputs into clean digital outputs via positive- and negative-going thresholds (VT+ = 2.0 V, VT− = 0.5–0.6 V at VCC = 4.5–5.5 V), delivering 0.35–1.6 V hysteresis depending on supply and temperature.

Its static characteristics are specified across -40 °C to +125 °C, with VOH ≥ 3.70 V and VOL ≤ 0.55 V at IO = ±8.0 mA, and dynamic performance validated under CL = 15 pF and 50 pF loads. The device uses Si-gate CMOS process with balanced output impedance and low ICC (≤40 μA at VCC = 5.5 V, all inputs static).

FAQ

What is the pin 1 location and marking code for XC7WT14DC,125?

Pin 1 is located at the lower-left corner of the TSSOP8 package, below the marking code "g14" printed on the top surface. The device uses SOT505-2 outline with 0.65 mm pitch; orientation follows JEDEC-standard pin 1 indicator (notch or dot). This marking and pinout match Nexperia's Rev. 6 datasheet Figure 4 and Table 2.

Can XC7WT14DC,125 operate at 3.3 V supply?

No - the XC7WT14DC,125 is specified only for VCC = 4.5 V to 5.5 V per Table 6. At 3.3 V, VT+ and VT− thresholds fall outside guaranteed range, hysteresis collapses below 0.3 V, and output drive drops below 4 mA, risking unreliable switching. For 3.3 V systems, consider NXH010P120MNF1 or SN74LVC14A.

How does the XC7WT14DC,125 handle slow input edges?

It transforms slow edges (e.g., 100 ns–10 μs rise/fall) into sharp transitions using defined VT+ (2.0 V) and VT− (0.5–0.6 V) thresholds, generating jitter-free outputs. Additional supply current ΔICC(AV) increases during transitions (up to 200 μA per input), but total ICC remains ≤40 μA in steady state per Table 7.

Is XC7WT14DC,125 automotive-qualified?

No - although rated for -40 °C to +125 °C, Nexperia explicitly states in Section 17 that XC7WT14DC,125 is "non-automotive qualified" and not tested to AEC-Q100. It lacks automotive-specific reliability testing, qualification reports, or PPAP documentation; use requires customer risk assessment for non-safety-critical cabin functions only.
