REG5608U中文资料LOW CAPACITANCE 18-Line SCSI ACTIVE TERMINATOR数据手册TI规格书

描述 Description

DESCRIPTION
The REG5608 is a low capacitance 18-line active terminator for SCSI (Small Computer Systems Interface) parallel bus systems. On-chip resistors and voltage regulator provide the prescribed SCSI bus termination. Low line capacitance (2pF) meets requirements for high data rate systems.
All terminations can be disconnected from the bus with a single logic control line. In the disconnect mode, output lines remain high impedance with or without power applied. This allows “hot socket” equipment plugging as required for “plug and play” applications.FEATURES
● ACTIVE 18-Line TERMINATOR
● 2pF CAPACITANCE PER LINE IMPORTANT FOR SCSI FAST-20
● ON-CHIP TERMINATION RESISTORS
● ALL TERMINATIONS DISCONNECT WITH SINGLE LOGIC SIGNAL
● 325mA CURRENT SINKING FOR ACTIVE NEGATION
● 22.4mA PER LINE DURING ASSERTION
● CURRENT LIMIT AND THERMAL LIMIT
● HOT-SOCKET CAPABLE
● 28-Lead SOIC and SSOP PACKAGES
