CD4069UBE CMOS Hex Inverter – Wide Voltage Range, Low-Power Logic IC
The CD4069UBE from Texas Instruments (TI) is a CMOS-compatible hex inverter integrating six independent buffer-free logic inverters in a single IC. It operates across a wide supply voltage range (3V to 18V), making it suitable for high-voltage digital systems, battery-powered devices, and industrial control applications. Key advantages include ultra-low input current (just 1µA max at 18V, 100nA at 25°C), ensuring minimal power consumption in always-on circuits. With a typical propagation delay of 30ns at 10V, it provides medium-speed switching, ideal for pulse shaping, oscillators, and clock generation. Its symmetrical output characteristics (tPHL = tPLH) ensure precise signal integrity, while the ±6.8mA output drive is sufficient for LED drivers and small loads. Compared to CD4009/CD4049 buffer-based inverters, the CD4069UBE IC Hex Inverter eliminates buffering stages, reducing power dissipation and board space. It excels in RC oscillators, sensor interfaces, and high-impedance amplifiers where power efficiency matters. Supporting an extended temperature range (-55°C to +125°C), it is also ideal for automotive, industrial, and military-grade electronics. Available in PDIP-14, SOIC-14, and TSSOP-14 packages, this IC is RoHS-compliant (except CDIP variants), offering flexibility for both prototyping and mass production. Whether used as a standalone signal inverter or part of a larger logic circuit, the CD4069UB delivers reliable performance with low quiescent current (<150µA) and high noise immunity.Key Specifications
