 The publisher Polytechnic (SP-B) appeared
The new book "Tsiftrovye Devices
GI Puchalski and TY Novoseltseva. By
Compared with the first edition (1990) have significantly 
increased. 

 It is unlikely that readers will satisfy ZF dry
academic review of the book.

 Predzhde all about the spirit of the book, I think,
all without exception had circuitry along with the authors of 
other technical publications make friends in the dark maze of 
medieval scholasticism, when a jumble of formulas is lost and 
the plot and the meaning and purpose of the material presented. 
Sometimes the only bearable conclusion of these editions is 
that the author is undoubtedly worthy of the degree of PhD, 
Doctor of Engineering, and etc. etc. and the book it is better 
not to touch. Read what's better-realties of the publishing 
house "Mir". This book compares favorably in this regard. In 
the middle 80, when digital technology efforts

amateur informal markets have been lifted taboos emerged as
simple, democratic and dohodchizhye publications devoted to 
this subject. Universal gained popularity Book VL Shilo

Preferred digital circuits. " Book
definitely perfect for students and people familiar with the 
slab of digital technology, but it interested. But the former

students become professionals and
ceases to meet the level of presentation ...

 "Digital devices are strange, but at the same time 
encouraging" mutant. " The depth and completeness of the 
collection of material, academic in the best sense of the 
words, the original edition (such powerful, detailed, strictly

and yet simple in presentation of mathematical tools, piercing 
all Fabric narrative the author has had

found even in translated editions) is combined with the 
necessary circuitry for practice-specific encyclopaedic 
information about the family of TTL / CMOS as tsokolevok ICs, 
tables, parameters and circuit studies and practical 
applications. These two hypostasis there are "inseparable and 
unmerged", allowing the reader obschatsya with a book on any 
available for his level.


 Now on specific features. I want to note the fact that the 
subject of a proper family SN74 in its entirety, as in series,

and by part types. Domestic
analogues are only (and not vice versa,
how it was made). While it is difficult to judge
As editor of the book (ie the number of typos), but judging by 
the first edition 1990. which has been investigated

the length and breadth, it is given sufficient attention. Even 
if it does not, a mistake committed in the background material 
can be easily removed by "voting", ie comparison with the same 
VN Shilo. Such an opportunity may give only the original 
edition (not compiled). These features make the book very 
useful not only for students and amateurs, but also for

repairers, service imports
(Background, the second part of the book) and domestic CEA (in 
which no glass and good methodological training and

razobratsya - corresponds to the first part).

 As it should be in every review, put a spoonful of honey into 
a barrel of tar. Although it is not so much fly in the 
ointment, as a reference to the some gaps in the narrative, 
which should be viewed as suggestions.

It is possible that the following
aspects of digital circuitry beyond
framework themes of the book, and are not included by the 
authors sobrazheniya integrity of the presentation.

So, no description interface
schemes orientirovnnnyh to work on a standard communication 
line. Formally, such IC may not apply to the SN74, but, in 
practice, are an integral part of the family and run by 
technology TTL (Govotya markups, TTL family of not zamkunto

for SN74). Colorful examples of such schemes
serve 559IP19 and IP20, a known
as MC1488 and MC1485A, without which manages almost no western 
circuitry. (In native penates usually fuss on standard SN74 or 
discrete components, significantly reducing reliability and 
adaptability) Another example - IC 1818VZH1 (F9401C) is a 
linear automaton. It would be appropriate to blee description 
in the appropriate section. Weakly lighting circuitry of the 
primary (usually quartz) generators, a large

as defining the parameters of digital devices. (It is well 
known in his time west "Problem cycles). Literate

design of digital devices as well
impossible without the dynamic parameters
(Instantaneous current-voltage characteristics for input / 
output base member of the family). Most of his idachno

can be represented in the form of diagrams de Birzherona. This 
is necessary because, unfortunately, is not always possible to 
do without adjusts the time delay RC-circuits

and utilization of output TL-PS In the analog switch on. It is 
obvious that now, when stop widespread plants, there is no 
feedback from the production (and respectively, and the 
transfer of emerging problems at the level of know-how) and 
this kind of blemishes are inevitable.


 But even more remarkable labor of authors,
which, no matter what, they wrote
this book. So in conclusion, I want to say that despite the 
placers in the book saynetologicheskoy shelves (literally 
"naukoyazychnoy") LSD-literature from IBM offers to your 
attention the book looks just snogosshibatelno. This book

has its own face, visible to the school - and this is our
national school.
