Not included i

11、n this document are device specific parameters and performance levels that the vendor must also supply for full device description. The purpose of this document is to provide a set of uniform data sheet parameters for the description of bus switch devices. This standard includes required parameters,

12、 test con-ditions, test levels, and measurement methods for data sheet descriptions of bus switch devices.2 Definitions for the purpose of this documentswitch device: A semiconductor logic device designed to connect or disconnect busses or control signals without active drivers in the connection pat
