50 CMOS IC Projects

CMOS IC's are probably the most versatile range of digital devices for use by the amateur enthusiast They are suitable for an extraordinarily wide range of applications and are now also some of the most inexpensive and easily available types of I.C.

In this book Mr. R. A. Penfold has designed and developed a number of interesting and useful projects which are divided into four general categories:

I Multivibrators

II Amplifiers and Oscillators

III Trigger Devices

IV Special Devices


COMPONENTS

The type numbers under which the CMOS I.C.s employed in the circuits in this book are sold have already been discussed, and details of the leadout arrangements have been given. Details of the other semiconductors which have been specified for projects are given in Figure 57.

There are many alternatives to the specified semiconductors, and suit able substitutes for the BC109 for instance, are BC169, B C184L, BC172, etc. However, as the specified types are probably the cheapest and most widely available types, there is little point in making a substitution unless a suitable alternative is already to hand.

All resistors are ordinary 1/4, 1/3 or half watt types of the usual tolerances (5% up to 1 Meg. and 10% above 1 Meg.) except where noted otherwise in the text. Potentiometers are all carbon types, and they are either logarithmic or linear (log. or lin.), the circuit diagram indicating which is appropriate for each one. Presets can be virtually any type and are chosen to best suit the particular layout used. is appropriate for each one. Presets can be virtually any type and are chosen to best suit the particular layout used.

Except where specified otherwise in the text, capacitors up to about 330 nF (0.33 mfd) can be any plastic foil or ceramic type having a tolerance of 20% or better. Some ceramic types have very wide tolerances and are best avoided by inexperienced constructors who are in doubt as to their suitability for a particular circuit.

Trimmer capacitors are used in some of the R.F. oscillators, and at the relatively low frequencies involved in these it is not necessary to use any special type. Any trimmer having the specified maximum capacitance and a reasonably low minimum capacitance should be satisfactory.
