GENERAL DESCRIPTION

The ML6599 BiCMOS 9 line SCSI terminator provides active termination in SCSI systems using single ended drivers and receivers. Active SCSI termination helps to effectively control analog transmission line effects such as ringing, noise, crosstalk, and ground bounce. In addition, the ML6599 provides support for hot-insertability on the SCSI bus.

FEATURES

■ Fully monolithic IC solution providing active termination for 9 lines of the SCSI bus

■ Provides on board support for hot-insertability on the SCSI bus

■ Low dropout voltage (1V) linear regulator, trimmed for accurate termination current

■ Output capacitance typically < 5pF

■ Disconnect mode — logic pin to disconnect terminator from the SCSI bus, <100µA

■ Current sinking — can sink current in excess of 10mA per line to handle active negation driver overshoots above 2.85V

■ Negative clamping on all lines to handle signal assertion transients

■ Regulator can source 200mA and sink 100mA while maintaining regulation

■ Current limit & thermal shutdown protection
