Nexperia USA Inc. HEF40106BTT,118

Overview

HEF40106BTT,118 from Nexperia is a hex inverting Schmitt trigger IC with six independent CMOS inverters, each featuring hysteresis (VT+ = 3.7 V / VT− = 3.0 V at VDD = 10 V), rail-to-rail output swing (VOH ≥ 9.95 V, VOL ≤ 0.05 V at VDD = 10 V), and operation across 3.0–15.0 V supply. It enables robust waveform shaping and oscillator design in industrial control interfaces and sensor signal conditioning circuits.

For engineers reviewing the HEF40106BTT,118 datasheet, HEF40106BTT,118 pinout, HEF40106BTT,118 application, or HEF40106BTT,118 equivalent, key selection criteria include input hysteresis voltage (VH = 0.7 V typ. at 10 V), propagation delay (tPHL = 35 ns max at VDD = 10 V, CL = 50 pF), operating temperature range (−40 °C to +125 °C), and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The HEF40106BTT implements six identical CMOS inverting Schmitt triggers with symmetrical input clamping diodes enabling safe interfacing to voltages exceeding VDD via current-limiting resistors. Each gate provides hysteresis defined by VT+ and VT− thresholds that scale linearly with supply voltage.

Its static characteristics guarantee VOH ≥ 9.95 V and VOL ≤ 0.05 V at VDD = 10 V with |IO| < 1 μA, while dynamic performance delivers tPHL/tPLH ≤ 35 ns and tTHL/tTLH ≤ 30 ns under 10 V/50 pF conditions - critical for stable multivibrator timing and noise-immune edge detection.

FAQ

Can HEF40106BTT,118 operate reliably at 15 V with full output drive capability?

Yes. The device is fully characterized at 15 V per Table 5 (Recommended Operating Conditions) and delivers VOH ≥ 14.95 V and VOL ≤ 0.05 V with |IO| < 1 μA. Output drive remains functional up to IOL = 2.4 mA at VO = 1.5 V, satisfying standard 4000-series load requirements under 15 V operation.

What is the minimum recommended decoupling capacitance for HEF40106BTT,118 in a 10 V application?

A 100 nF X7R ceramic capacitor placed within 5 mm of the VDD pin (Pin 14) and VSS pin (Pin 7) is specified in Nexperia's layout guidelines. This value ensures adequate high-frequency transient suppression for switching events up to 10 MHz, preventing supply rail collapse during simultaneous gate transitions.

Does HEF40106BTT,118 require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be tied to either VDD or VSS - floating inputs are prohibited due to CMOS latch-up risk and undefined logic states. Internal input clamp diodes do not eliminate this requirement; they only protect against overvoltage, not DC bias stability.

How does the hysteresis voltage (VH) change with supply voltage in HEF40106BTT,118?

VH scales approximately linearly with VDD: VH = 0.5 V at 5 V, 0.7 V at 10 V, and 0.9 V at 15 V (Table 11). This behavior ensures consistent noise margin percentage (~10–15 % of VDD) across the full operating range, maintaining reliable edge discrimination regardless of rail voltage.
