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. (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.)

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.
