11、rmulated under the cognizance of the JC-16 Committee on Interface Technology) 1 Scope This standard defines power supply voltage ranges, dc interface and switching parameters for a high speed, low voltage family of nonterminated digital circuits driving/driven by parts of the same family, or mixed f
12、amilies which comply with the input receiver specifications. The specifications in this standard represent a minimum set of interface specifications for CMOS compatible circuits. The purpose of this document is to provide a standard of specification for uniformity, multiplicity of sources, eliminati
13、on of confusion, and ease of device specification and design by users. Clause 2.3 describes normal dc electrical characteristics and clause 2.4 (added in revision A) describes the optional characteristics for Schmitt trigger operation. 2 Standard specifications All voltages are referenced to ground
