Texas Instruments CD4069UBE CMOS Hex Inverter IC, 14-Pin DIP

The Texas Instruments CD4069UBE is a fundamental building block in digital logic design. This monolithic CMOS integrated circuit contains six independent inverter gates within a single 14-pin Dual In-line Package (DIP), offering an economical and space-saving solution for a wide array of general-purpose logic applications. Its primary function is to perform logic inversion, where a HIGH input signal becomes a LOW output, and vice versa.

Engineered for versatility, this hex inverter operates across a broad supply voltage range from 3V to 18V, making it compatible with various logic families and power supplies. It features standardized symmetrical output characteristics and exhibits an extremely high input impedance, drawing a maximum input current of just 1µA across the full operating temperature range. This characteristic makes it ideal for interfacing with high-impedance sensors or creating low-power oscillator circuits.

The CD4069UBE is rigorously tested, including 100% testing for quiescent current at 20V, ensuring reliability and performance consistency. It is constructed to meet the stringent requirements of the JEDEC standard JESD 13B and can operate in demanding environments with a temperature range from -55°C to 125°C.

Key Applications

This versatile IC is commonly employed as a basic logic gate for signal inversion, pulse shaping, and waveform generation. Its high input impedance makes it suitable for use in analogue circuits as a simple linear amplifier. One of its most frequent uses is in the creation of crystal or RC-based oscillators and clock pulse generators, forming the heartbeat of many digital systems. It is also perfect for buffering signals, cleaning up noisy digital waveforms, and implementing simple logic functions in prototype boards and educational settings.
