REG5608E

LOW CAPACITANCE 18-Line SCSI ACTIVE TERMINATOR

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.
