<p>MIL-HDBK-1331, DEPARTMENT OF DEFENSE: HANDBOOK FOR PARAMETERS TO BE CONTROLLED FOR THE SPECIFICATION OF MICROCIRCUITS (30 OCT 1995) [SUPERSEDING MIL-STD-1331]., This handbook describes the parameters required as a minimum for the specification of microcircuits. Parameters, rather than circuits, are considered because circuits vary with the manufacturers involved. Further, circuit designs should be subject to change if improvement results as long as the affected designs are compatible and fully interchangeable. The specific objectives of this document are as follows: a. To provide the minimum parameters that should be specified to ensure adequate evaluation of circuit design and performance. b. To provide maximum commonality of parameters for purpose of test and measurement, within and between major classes of microcircuit types and to allow the recognition of interface problems between types of microcircuits. c. To provide standard abbreviations, definitions and symbols pertinent to the specification of microcircuits. d. To promote maximum interchangeability and compatibility between microcircuits types.</p>
