DESCRIPTION
The LX5107 is a nine-line active terminator for the SCSI parallel bus. This SCSI standard recommends active termination at both ends of the SCSI bus.
During disconnect mode, the LX5107 requires a meager 30µA of supply current while offering only 3.0pF of output capacitance. To enter this low-power mode, the disconnect pin should be driven low thereby disconnecting the terminating resistors and placing the internal low dropout regulator into low-power mode. In disconnect mode, each termination line presents a high impedance to the SCSI bus with the overall effect being to preserve high signal integrity and yield subsequent reliable, error free communications.
