10、7559 JEDEC Standard No. 73-1Page 1STANDARD FOR DESCRIPTION OF 3.3 V NFET BUS SWITCH DEVICES(From Board Ballot JCB-00-98, formulated under the cognizance of the JC-40 Committee on Digal Logic.)1 ScopeThis standard covers specifications for a family of 3.3 V NMOS FET bus switch devices. 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
