  1. CD4007 CMOS Pairs Electronic Design Laboratory

  2. Overview • CD4007 Dual Complementary Pair Plus Inverter • Rise Time and Fall Time • Design Number Documents • Six Configurations

  3. CD4007

  4. CD4007 Reference Inverter and Center Pair

  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.
