Nexperia USA Inc. XC7WH14DC,125

Overview

XC7WH14DC,125 from Nexperia is a triple inverting Schmitt trigger IC in VSSOP8 package, delivering sharp signal conditioning for noisy environments with 3 independent hysteresis-input buffers. It operates from 2.0 V to 5.5 V, supports -40 °C to +125 °C ambient range, and provides 3.2 ns typical propagation delay at 5.0 V with 15 pF load - used in waveform shaping, relaxation oscillators, and multivibrator circuits.

For engineers reviewing the XC7WH14DC,125 datasheet, XC7WH14DC,125 pinout, XC7WH14DC,125 application, or XC7WH14DC,125 equivalent, key selection criteria include input hysteresis voltage (0.45–1.6 V), symmetrical output drive (±8 mA), ESD robustness (HBM >2000 V), and VSSOP8 thermal derating (4.9 mW/K above 99 °C).

Technical Context

The XC7WH14DC,125 implements three independent CMOS-based Schmitt trigger inverters with defined VT+ (positive-going threshold) and VT− (negative-going threshold) to reject noise on slow-rising/falling inputs. Each channel features identical transfer characteristics and balanced tPLH/tPHL propagation delays.

Its static behavior is characterized by rail-to-rail input compatibility (VI = 0 to VCC), low ICC (<10 μA at 25 °C), and hysteresis voltage (VH) ranging from 0.45 V to 1.6 V depending on supply voltage - enabling reliable oscillation in RC-based astable configurations without external feedback components.

FAQ

What is the minimum supply voltage for reliable Schmitt trigger operation?

The XC7WH14DC,125 guarantees full Schmitt functionality down to 2.0 V supply, with validated VT+ and VT− thresholds and hysteresis across the entire -40 °C to +125 °C range. Below 2.0 V, input thresholds become undefined and output drive degrades significantly.

Can this device drive a 50 pF load at 10 MHz without signal degradation?

Yes - at VCC = 5.0 V, the device delivers 3.2 ns typical tpd into 15 pF and 4.6 ns into 50 pF, with ±8 mA drive strength ensuring clean edges. Total dynamic power remains below 1.2 mW at 10 MHz, well within its 250 mW Ptot rating at 25 °C.

Is the VSSOP8 package thermally enhanced for continuous operation at +125 °C?

The SOT765-1 VSSOP8 package has a thermal resistance θJA of ~204 K/W and linear power derating of 4.9 mW/K above 99 °C. At +125 °C ambient, maximum allowed Ptot drops to ~125 mW - sufficient for typical 3-channel operation at 5 V/1 MHz (≈0.3 mW total).

How does the input hysteresis vary with supply voltage?

VH increases linearly with VCC: 0.3 V min. at 3.0 V, 0.45 V min. at 5.5 V. VT+ tracks ~70% of VCC and VT− tracks ~30% of VCC across the full operating range, maintaining consistent noise margin percentage regardless of rail voltage.
