SCSI active terminator
BH9595FP-Y
1/7
These SCSI active terminators, developed as a substitute for conventional discrete terminators, maintain good
consistency between VM level (2.85V) and GND level (0V) and between VM level and VDD level, and have extremely
low power consumption, dropping to a maximum of 90 milliwatts at standby (compared to the maximum of 990 milliwatts
used by conventional resistance terminators ). These SCSI active terminators electrically control SCSI lines, connecting
and disengaging the terminating resistor by electrically controlling the enable pin.

Application
PC and peripheral appliances, OA appliances, Disk drive appliances
!
Features
1) Internal 2.85V power supply and push-pull operation, for good consistency at all signal levels.
2) Enable pin for terminator enabling and disconnecting, facilitating SCSI network construction.
3) Low power consumption, ideal for energy-saving systems.
Power consumption (during standby)
SCISI active Terminators : 90mW
Conventional resistor terminators : 990mW
Power consumption (25% duty)
SCISI active Terminators : 614mW
Conventional resistor terminators : 15/190mW
Significant reductions in power consumption are possible by using this terminator.
4) Wide operating range.
TERM power : 4.0
