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.
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.
The REG5608 is available in 28-lead SOIC and
fine-pitch SSOP packages and is specified for 0
°
C to
70
°
C operation.
