HEX Inverter CD4069UBE

The HEX Inverter CD4069UBE is a CMOS 4000-series IC with six independent inverters (NOT gates) in a 14-pin plastic DIP package. Each inverter outputs the opposite logic level of its input. The UB in the part number means the gates are unbuffered single-stage inverters, which makes this chip a favourite for crystal and RC oscillators and simple linear amplifiers as well as everyday logic.

What's in the Box

• 1 × CD4069UBE hex inverter IC

Tip: For a simple RC oscillator, connect two inverters in series with a resistor and capacitor feedback network. Tie unused inputs to VDD or VSS, and add a 100 nF decoupling capacitor between pins 14 and 7.
