Nexperia USA Inc. HEF40106BTT-Q100J

Overview

HEF40106BTT-Q100 from Nexperia is a hex inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 3.0 V to 15.0 V. It provides six independent hysteresis-equipped inverters with input clamp diodes enabling overvoltage-tolerant interfacing, symmetrical CMOS output drive (±4.2 mA at 15 V), and propagation delays as low as 22 ns at 15 V. It is used in automotive waveform conditioning circuits such as engine control timing signal cleanup.

For engineers reviewing the HEF40106BTT-Q100 datasheet, HEF40106BTT-Q100 pinout, HEF40106BTT-Q100 application, or HEF40106BTT-Q100 equivalent, key selection considerations include Schmitt trigger hysteresis voltage (0.9–1.8 V), VT+ threshold range (4.9–11.0 V at 15 V), TSSOP14 thermal derating (7.3 mW/K above 81 °C), and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

The HEF40106BTT-Q100 implements six independent CMOS inverter stages, each with Schmitt-trigger input circuitry providing positive and negative-going thresholds (VT+ and VT−) and hysteresis (VH) to reject noise on slow-rising or noisy signals. Its static operation supports DC-coupled logic level translation across 3–15 V rails without clocking constraints.

Each channel features input clamp diodes referenced to VDD and VSS, allowing safe interface to voltages beyond the supply rail when used with current-limiting resistors. Output stages deliver rail-to-rail swing with symmetrical sourcing/sinking capability and are characterized for dynamic loading up to 50 pF at 25 °C.

FAQ

What is the maximum allowable input voltage when VDD = 12 V?

The absolute maximum input voltage is VDD + 0.5 V = 12.5 V, per Table 4 limiting values. Input clamp diodes conduct above this level, so external current-limiting resistors must restrict IIK to ±10 mA. For sustained 24 V sensor interfaces, a 1.2 kΩ resistor limits peak current to ~10 mA at 24.5 V, satisfying the specification.

Can HEF40106BTT-Q100 drive a 100 pF load at 10 MHz?

Yes. At VDD = 15 V and CL = 100 pF, tPLH/tPHL remains ≤ 60 ns (Table 7), supporting 10 MHz fundamental frequencies. Dynamic power dissipation would be ~2.1 mW per active gate (PD = 20000 × 10 + 10 × 100 × 225 = 222500 μW), well within the 500 mW total package limit at +125 °C.

How does hysteresis change with supply voltage?

VH increases with VDD: 0.5–0.8 V at 5 V, 0.7–1.3 V at 10 V, and 0.9–1.8 V at 15 V (Table 11). This scaling ensures consistent noise margin percentage-wise across the full 3–15 V range, critical for reliable operation as vehicle battery voltage varies from 12 V (engine off) to 14.5 V (charging).

Is thermal derating required for continuous operation at 125 °C ambient?

Yes. For the TSSOP14 package (SOT402-1), Ptot derates linearly at 7.3 mW/K above 81 °C. At 125 °C ambient, derating is (125 − 81) × 7.3 = 321 mW, leaving 500 − 321 = 179 mW usable total power. With six gates active at 15 V, average per-gate dissipation must stay below ~30 mW to remain within limit.
