STMicroelectronics HCF4069UBEY

Overview

HCF4069UBEY from STMicroelectronics is a hex inverter IC fabricated in CMOS technology, housed in a 14-pin plastic DIP package. It provides six independent inverters with symmetrical output drive, 30 ns typical propagation delay at 10 V, ±100 nA max input leakage at 18 V, and operates across 3–20 V supply range-used in logic level translation, signal inversion, and oscillator circuits in industrial control and instrumentation.

For engineers reviewing the HCF4069UBEY datasheet, HCF4069UBEY pinout, HCF4069UBEY application, or HCF4069UBEY equivalent, key selection criteria include VDD operating range (3–20 V), output drive capability (±3.2 mA at 5 V), noise margin (≥2.5 V at 15 V), and temperature rating (–55°C to +125°C) for robustness in wide-voltage embedded systems.

Technical Context

The HCF4069UBEY implements six unbuffered CMOS inverter stages with rail-to-rail output swing and matched rise/fall times. Its design supports direct interface between disparate logic families (e.g., TTL-to-CMOS) via adjustable VDD and high noise immunity (2.5 V min at 15 V).

Each inverter features low quiescent current (0.01 µA typ. at 5 V), input protection diodes, and guaranteed operation up to 20 V absolute max supply-enabling use in battery-powered and industrial power-rail tolerant applications without external level-shifting.

FAQ

What is the maximum supply voltage the HCF4069UBEY can withstand continuously?

The HCF4069UBEY has an absolute maximum VDD rating of +22 V, but continuous operation is specified up to 20 V per JEDEC JESD13B. Operating at 20 V is fully characterized for DC and dynamic parameters-including propagation delay, output drive, and leakage-across –55°C to +125°C.

Can the HCF4069UBEY drive a 50 pF capacitive load at 1 MHz?

Yes. The datasheet specifies dynamic performance with CL = 50 pF, RL = 200 kΩ, and tr/tf = 20 ns. At VDD = 10 V, tPLH/tPHL is 30 ns (typ.), supporting reliable 1 MHz square-wave generation with adequate edge fidelity and minimal overshoot.

Does the HCF4069UBEY include input protection diodes?

Yes. The input equivalent circuit shown in the datasheet includes clamping diodes to VDD and VSS, limiting input voltage to –0.5 V to VDD + 0.5 V. This protects against transient overvoltage and ESD events up to ±2 kV (HBM), consistent with standard CMOS B-series construction.

Is the HCF4069UBEY pin-compatible with the CD4069UB?

Yes. Both devices use identical 14-pin DIP/SOP footprints and share the same pin assignment: inputs on pins 1,3,5,9,11,13; outputs on 2,4,6,8,10,12; VSS on 7; VDD on 14. Electrical behavior differs slightly-HCF4069UBEY offers faster tPD and lower II-but mechanical and logical replacement is direct.
