LOW CAPACITANCE 18-Line SCSI  
ACTIVE TERMINATOR  
FEATURES  
DESCRIPTION  
ACTIVE 18-Line TERMINATOR  
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.  
2pF CAPACITANCE PER LINE  
IMPORTANT FOR SCSI FAST-20  
ON-CHIP TERMINATION RESISTORS  
ALL TERMINATIONS DISCONNECT WITH  
SINGLE LOGIC SIGNAL  
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.  
325mA CURRENT SINKING FOR ACTIVE  
NEGATION  
22.4mA PER LINE DURING ASSERTION  
CURRENT LIMIT AND THERMAL LIMIT  
HOT-SOCKET CAPABLE  
The internal voltage regulator is temperature-compen-  
sated to assure proper termination characteristics over  
a wide operating range. Output current and thermal  
limit circuitry protect against damage.  
28-Lead SOIC and SSOP PACKAGES  
The REG5608 is available in 28-lead SOIC and  
fine-pitch SSOP packages and is specified for 0°C to  
70°C operation.
