Figure 3.1 LSI8751D Mechanical Drawing

3.1.2 Electrical Characteristics

The LSI8751D maximum power requirements, including SCSI

TERMPWR, under normal operation, are shown in Table 1.1:

Under abnormal conditions, such as a short on SCSI TERMPWR, +5 V

current may be higher. At temperatures of at least 25 °C, a current of

4 A is sustained no longer than 30 seconds before the self-resetting

TERMPWR short circuit protection device opens.

LSI53C875J

127.00 (REF) (5.00 (REF))

82.55 (REF) (3.25 (REF))

All dimensions are given in millimeters and (inches).
