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 : 90mW (compared to 990mW for conventional resistor terminators) Power consumption at 25% duty : 614mW (compared to 1,360mW for convention resistor terminators) Significant reductions in power consumption are possible.
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. ApplicationCompact disk drives, optical disk drives, CD-ROM drives, tape drives, personal computers (including laptop computers and notebook computers), workstations, mainframes, laser printers, plotters.

DescriptionThese SCSI active terminators BH9596FP-Y, developed as a substitute for conventional discrete terminators, maintain good con- sistency 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 milli- watts used by conventional resistance terminators). These SCSI active terminators BH9596FP-Y electrically control SCSI lines, connecting and disengaging the terminating resistor by electrically controlling the enable pin. (The enable pin is enabled at the HIGH level and switched to the High-Z state by the LOW level in the BH9595 and by the HIGH level in the BH9596, completely disconnecting the SCSI line from the SCSI terminator.)
These SCSI active terminators BH9596FP-Y allow for the configuration of flexible, energy-saving SCSI networks, and are ideal for notebook computers, hard disk drives and a wide range of other products with SCSI capabilities.
