SCSI active terminator

BH9595FP-Y

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∼5.5V (Transient : 6.0V)

5) Thin, microminiature design, ideal for space-saving applications.

Package body size : 13.6×5.4×1.9mm

6) Active termination of 18-line SCSI.

7) Internal thermal shutdown circuit.

8) Compatibility with SCSI-I and SCSI-II.
