Z53C8003VSC集成電路（IC）的信號端接器規(guī)格書PDF中文資料

Z53C8003VSC屬于集成電路（IC）的信號端接器。由Zilog, Inc.制造生產(chǎn)的Z53C8003VSC信號端接器信號端接器用于向信號路徑提供電氣端點，以防止信號反射回電路而引起干擾。類型有電纜、DDCA、SCSI、HVD、SE、LVD、串行和 USB，端接數(shù)量為 1、2、6、8、9、14、15、18 或 27。

GENERAL DESCRIPTION

The Z53C80 SCSI (Small Computer System Interface) controller is designed to implement the SCSI protocol as defined by the ANSI X3.131-1986 standard, and it is fully compatible with the industry standard 5380. The device is capable of operating both as a Target and as an Initiator. Special high-current open-drain outputs enable it to directly interface to the SCSI bus. The Z53C80 has the necessary interface hook-ups which allow the system CPU to communicate with it as with any other peripheral device. The CPU can read from, or write to, the SCSI registers which are addressed as standard or memory-mapped I/Os.
