GB/T 20295-2014Application of symbols for binary logic and analogue elements (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard is equivalent to using IEC TR61734:2006 "binary logic elements, and analog component symbols of applications", and made editorial modify.

This standard replaces GB/T 20295-2006 "GB/T 4728.12 and GB/T 4728.13 standard application." this standard compared with GB/T 20295-2006 main changes are as follows.

--- Standard name to the IEC 61734:2006 the same name. "binary logic elements, and analog component symbols of application";

--- Full of symbols of the new formulation increases GB/T 4728 way of expression;

--- Increasing the reference standard GB/T 20296-2012 "law and integrated circuit memory symbol";

--- In Chapter 3, we added the sentence. use-related memory function and method of input or output and focused on defining symbols GB/T 20296 provides.

--- Original 11 Table 1 instead of the original images are adjusted accordingly Figure 11 after a sequence number order.

1 Scope

This standard specifies the application of GB/T 4728.12 and GB/T 4728.13 draw graphical symbols rules that allow a graphic symbol prepared Cause, and can accurately represent the function. This standard has also developed 4728.13 does not include the additional provisions in GB/T 4728.12 and GB/T , its inclusion was recommended to GB/T 4728.12 and GB/T 4728.13, and to draw symbols to help.

This standard applies to the field of design and simulation application binary logic elements element symbol.

GB/T 4728.12 and GB/T 4728.13 were provided for in Rule binary logic elements, and analog components of graphical symbols for Under different circumstances indicate feature provides an alternative method.
