NXP Semiconductors XC7WT14GT,115

Overview

XC7WT14GT,115 from Nexperia is a triple inverting Schmitt trigger IC in XSON8 (SOT833-1) package, designed for noise-immune signal conditioning in digital systems. It provides three independent hysteresis-input buffers with VT+ = 2.0 V and VT− = 0.5–0.6 V at 4.5–5.5 V supply, propagation delay ≤9.0 ns (CL = 50 pF), and operates across −40 °C to +125 °C. Used in waveform shaping and relaxation oscillators.

For engineers reviewing the XC7WT14GT,115 datasheet, XC7WT14GT,115 pinout, XC7WT14GT,115 application, or XC7WT14GT,115 equivalent, key selection factors include input hysteresis voltage (VH = 0.4–1.6 V), symmetrical output drive (±8 mA), ESD robustness (HBM >2000 V), and TSSOP8/XSON8 package compatibility in space-constrained industrial timing circuits.

Technical Context

The XC7WT14GT,115 implements three independent CMOS Schmitt-trigger inverters using Si-gate technology, each with defined positive-going (VT+) and negative-going (VT−) input thresholds to reject noise on slow-rising/falling signals. Its transfer characteristic exhibits fixed hysteresis (VH) that scales with supply voltage - 0.4–1.4 V at VCC = 4.5 V and 0.4–1.6 V at VCC = 5.5 V.

Dynamic behavior is characterized by matched tPLH/tPHL propagation delays (≤9.0 ns at CL = 50 pF, VCC = 4.5–5.5 V), low power dissipation capacitance (CPD = 12 pF per buffer), and balanced output impedance enabling clean edge regeneration without ringing. Input clamping and output current limits comply with IEC 60134 absolute maximum ratings.

FAQ

What is the minimum recommended supply bypass capacitance for XC7WT14GT,115?

A 100 nF ceramic capacitor placed within 3 mm of the VCC and GND pins is required to suppress high-frequency supply transients induced by simultaneous switching of all three outputs. This value is validated per Nexperia's layout guidelines for XSON8 packages and ensures stable tPD performance under dynamic load conditions.

Can XC7WT14GT,115 operate reliably at 3.3 V supply?

No - the device is specified only for 4.5 V to 5.5 V operation per Table 6. At 3.3 V, VT+ and VT− thresholds fall outside guaranteed range, hysteresis collapses below 0.3 V, and output drive degrades below 4 mA, violating functional integrity. Use SN74LVC1G14 for 3.3 V systems.

How does the XC7WT14GT,115 handle floating inputs?

Inputs must never be left floating: each 1A/2A/3A pin has no internal pull-up/down. Unconnected inputs cause undefined output states and increased ICC due to linear-region conduction in input MOSFETs. External 10 kΩ pull-up or pull-down resistors are mandatory for unused channels.

Is the XC7WT14GT,115 pin-compatible with XC7WT14DP (TSSOP8)?

Yes - both share identical pin numbering and function mapping per Figure 4 and Table 3: Pin 1 = 1A, Pin 2 = 3Y, Pin 3 = 2A, Pin 4 = GND, Pin 5 = 2Y, Pin 6 = 3A, Pin 7 = 1Y, Pin 8 = VCC. Footprint differs (XSON8 vs TSSOP8), but schematic symbols and net assignments are interchangeable.
