Nexperia USA Inc. HEF4069UBT-Q100J

Overview

HEF4069UBT-Q100 from Nexperia is a hex unbuffered CMOS inverter qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 3.0 V to 15.0 V. It features six independent inverters with input clamp diodes enabling interface to voltages exceeding VDD via current-limiting resistors, and delivers symmetrical output drive (±2.4 mA at 15 V) for oscillator and analog amplifier applications.

For engineers reviewing the HEF4069UBT-Q100 datasheet, HEF4069UBT-Q100 pinout, HEF4069UBT-Q100 application, or HEF4069UBT-Q100 equivalent, this page provides verified functional identity, SO14 package mapping, automotive-grade thermal and ESD specifications (HBM >2000 V, CDM >1000 V), and validated oscillator/analog use cases per Nexperia's Rev. 4 data sheet.

Technical Context

This device implements six independent unbuffered CMOS inverters-each with no internal gain staging-enabling direct use as analog amplifiers when biased in the linear region. Its input clamp diodes allow safe overvoltage tolerance up to VDD + 0.5 V, supporting robust interfacing in noisy automotive environments.

Propagation delay ranges from 15 ns to 90 ns depending on VDD and load capacitance (CL), with extrapolation formulas provided (e.g., tPHL = 7 ns + 0.16 ns/pF × CL at 15 V). Output transition times are similarly CL-dependent, ensuring predictable timing behavior across 5–15 V operation.

FAQ

Is HEF4069UBT-Q100 pin-compatible with standard 4069B devices?

Yes-HEF4069UBT-Q100 uses the industry-standard SO14 pinout (SOT108-1) matching generic CD4069UB and 74HC04 packages: pins 1–13 alternate between inputs and outputs, with VSS at pin 7 and VDD at pin 14. No adapter or layout change is needed for drop-in replacement in existing 4069B footprints.

Can HEF4069UBT-Q100 operate as an analog amplifier?

Yes-its unbuffered CMOS structure allows stable linear-region biasing. Per Figure 11 and Table 5, applying a 560 kΩ feedback resistor between output and input achieves >25 dB gain at 15 V, with transconductance up to 10 mA/V (Fig. 12), making it suitable for low-frequency sensor signal conditioning without external op-amps.

What is the maximum capacitive load HEF4069UBT-Q100 can drive reliably?

Dynamic characteristics specify test conditions up to 50 pF (Table 8), and propagation delay scales predictably with CL (e.g., tPHL = 7 ns + 0.16 ns/pF × CL at 15 V). For reliable 10 MHz crystal oscillation (Fig. 8), total load-including PCB trace, probe, and external capacitors-must stay ≤50 pF to meet timing specs.

Does HEF4069UBT-Q100 require external pull-up or pull-down resistors on unused inputs?

No-unused inputs must be tied to VDD or VSS to prevent floating states and increased supply current. The datasheet explicitly warns against leaving inputs unconnected (Section 8), as CMOS inputs exhibit high impedance and susceptibility to noise-induced switching, which raises IDD and causes erratic output behavior.
