Nexperia USA Inc. HEF4069UBTT-Q100J

Overview

HEF4069UBTT-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified hex unbuffered CMOS inverter, operating across 3.0 V to 15.0 V supply voltage with input clamping diodes enabling overvoltage-tolerant interfacing. It delivers symmetrical output drive (±2.4 mA at 15 V), low static current (≤30 μA at 125 °C), and propagation delays as low as 15 ns (15 V, CL = 50 pF), used in automotive oscillator circuits and analog amplifier stages.

For engineers reviewing the HEF4069UBTT-Q100 datasheet, HEF4069UBTT-Q100 pinout, HEF4069UBTT-Q100 application, or HEF4069UBTT-Q100 equivalent, key selection criteria include its unbuffered inverter topology, TSSOP14 package thermal derating (7.3 mW/K above 81 °C), -40 °C to +125 °C automotive temperature range, and input/output clamping current limits (±10 mA).

Technical Context

This device implements six independent unbuffered CMOS inverters on a single die, each featuring integrated input clamp diodes for robust interfacing to signals exceeding VDD. Its unbuffered architecture provides high gain and nonlinear transfer characteristics suitable for oscillator and analog amplifier functions-not optimized for logic fanout or noise margin in digital switching.

It operates fully statically with no minimum clock frequency requirement, supports three standard supply rails (5 V/10 V/15 V), and exhibits rail-to-rail output swing with typical VOH = 14.95 V and VOL = 0.05 V at 15 V. Dynamic performance scales predictably with load capacitance via published extrapolation formulas (e.g., tPHL = 7 ns + 0.16 ns/pF × CL).

FAQ

What distinguishes HEF4069UBTT-Q100 from buffered hex inverters like SN74HC04?

The HEF4069UBTT-Q100 uses an unbuffered inverter structure, delivering high open-loop gain and nonlinear transfer characteristics essential for oscillator and analog amplifier applications. Buffered inverters like SN74HC04 prioritize logic-level integrity and fanout, sacrificing gain and linearity-making them unsuitable for crystal oscillators or linear biasing.

Can HEF4069UBTT-Q100 be used as a linear amplifier, and what biasing is required?

Yes-it can operate as a transconductance amplifier when DC-biased in its linear region using a high-value feedback resistor (e.g., 330 kΩ) between output and input. At 15 V supply, typical voltage gain is ~5×, with forward transconductance peaking near 7.5 mA/V. No external active components are needed.

How does the input clamping diode functionality impact circuit design?

The integrated clamp diodes allow safe connection of inputs to voltages up to VDD + 0.5 V or VSS − 0.5 V, provided external series resistors limit current to ≤±10 mA. This eliminates need for discrete clamping diodes in sensor interfaces exposed to automotive load-dump or jump-start transients.

Why is TSSOP14 (SOT402-1) preferred over SO14 (SOT108-1) for HEF4069UBTT-Q100?

The TSSOP14 package offers superior thermal performance in high-density automotive PCB layouts: its smaller footprint (4.4 mm width vs. 3.9 mm) and lower thermal resistance enable higher power dissipation before derating begins (starts at 81 °C vs. 100 °C for SO14), critical for sustained operation at +125 °C ambient.
