适用范围：This standard ( Part 5/Section 6 ) gives ratings and characteristics that are required to specify integrated circuits in which certain terminals, designated switch output terminals, can be caused either to reproduce the signal at the designated switch input terminals, or to be isolated from them by application of suitable electrical control signal(s) to the control termi-nals). The integrated circuit package contains switching element(s) and the associated control circuit(s). The switching elements may be controlled by one or more inputs and the control input may be analogue (differential) or digital. Examples of analogue switching circuits are as follows:1) Single analogue switching circuits having one switching element controlled by one control circuit.2) Multiple-channel analogue switching circuits:a) In which the switches are independent and each switching element is control-led by its own separate control circuit.b) In which a group of analogue switch-ing circuit is controlled by a single control circuit. The circuit may contain one or more groups of switch-ing elements.3) Multiplexing or demultiplexing analogue switching circuits having one or more analogue signal input terminals that can be selectively connected by a switch control circuit to one or more analogue signal output terminals.It is possible that other types of analogue signal switching circuits will either be covered by this section or by others.This standard covers both bipolar and FET switches.This standard should not be used when the constituent parts of the circuit can be specified adequately by other existing sections of Publi-cations on essential ratings and characteristics. For example, transistors that, while within thepackage, can be accessed separately via available terminations, should be specified separately according to the relevant specification.
