5 Warnings Don’t subject CD4007 to high voltages or static electricity.
Store CD4007 in an anti-static bag or in anti-static foam. Momentarily touch a metal part of the workbench to discharge yourself before handling the part or touching the leads. Never let voltage on any pin be more positive than pin 14 or more negative than pin 7. The circuit may “latch up”— possibly causing permanent damage.

6 Warnings Always connect pin 7 (substrate for n-channel transistors) to your negative supply voltage and pin 14 (substrate for p-channel transistors) to your positive supply voltage. Connect or turn-on the supply voltages (pins 7 & 14) before any other voltages in your circuit. For added safety, ground any unused inputs.
