1.7 Fourfold NAND-Gate 4011

An integrated circuit (IC) contains many components in one casing. The

4011 is a CMOS-IC with four NAND-gates. The IC is protected well

against electrostatic discharge and does not need to be treated with

any special care. Make sure that the operating voltage is connected in

the correct direction. If you install the IC in the wrong direction, it will

heat up too much and be destroyed. When first inserting into the

pinboard, the 14 connection legs must be aligned in parallel.

1.8 Two-Fold JK-Flipflop 4027

The 4027 is a CMOS-IC with 16 connections. It contains two

independent JK flipflops. As in all ICs, particularly correct connection of
