NXP Semiconductors HEF4069UBT,013

Overview

HEF4069UBT,013 from Nexperia is a hex unbuffered CMOS inverter IC operating from 3.0 V to 15.0 V supply, featuring six independent inverting gates with input clamp diodes, symmetrical output drive (±1.1 mA at 5 V), and guaranteed operation from −40 °C to +125 °C - used in oscillator circuits, analog amplifiers, and logic-level translation.

For engineers reviewing the HEF4069UBT,013 datasheet, HEF4069UBT,013 pinout, HEF4069UBT,013 application, or HEF4069UBT,013 equivalent, this device is selected for low-power unbuffered inversion where propagation delay (15–90 ns depending on VDD and load), rail-to-rail output swing, and wide-voltage compatibility are critical in timing and signal conditioning designs.

Technical Context

The HEF4069UBT,013 implements six identical unbuffered inverter stages using standard CMOS technology, each with direct gate-to-drain coupling and no internal buffering - enabling high gain and analog amplifier capability when biased in linear region. Input clamp diodes allow safe interfacing to voltages beyond VDD when used with current-limiting resistors.

It operates fully statically with zero static current draw at steady-state logic levels, and exhibits voltage-dependent propagation delay (e.g., 15 ns typical at 15 V/50 pF) and output transition times governed by load capacitance and supply voltage per defined extrapolation formulas.

FAQ

Can HEF4069UBT,013 be used as an analog amplifier?

Yes - its unbuffered architecture allows DC biasing into the linear region (Fig. 11). With a 330 kΩ feedback resistor and 560 kΩ bias network, it delivers voltage gain up to 75× at 15 V supply (Fig. 9), confirmed in Section 11 and Fig. 12 of the datasheet.

What is the maximum recommended load capacitance for stable oscillator operation?

For crystal oscillator designs (Fig. 8), load capacitance should remain ≤ 22 pF per inverter stage. For RC oscillators (Fig. 7), total node capacitance including stray C2 must satisfy R2 × C2 ≪ R1 × C1; typical design uses ≤ 50 pF total load per inverter per Table 8 test conditions.

Does HEF4069UBT,013 support 3.3 V operation?

Yes - the recommended operating range starts at 3.0 V (Table 4). At 3.3 V, VOH ≥ 3.25 V and VOL ≤ 0.05 V are guaranteed (Table 5), and propagation delay remains within specification (extrapolated tPHL ≈ 65 ns at CL = 50 pF using formula in Table 6).

How does the input clamp diode affect interfacing with 12 V signals on a 5 V supply?

Clamp diodes limit input voltage to VSS − 0.5 V and VDD + 0.5 V. To interface a 12 V signal to VDD = 5 V, a series current-limiting resistor ≥ (12 V − 5.5 V)/10 mA = 650 Ω is required to keep IIK ≤ ±10 mA (Table 3), ensuring safe operation without damage.
