DESCRIPTION
1
VREF
Reference Voltage. 2.85-volt reference in SE mode and 1.25-volt
reference in LVD mode; must be decoupled with a 4.7 F cap.
2-5, 7-12,
18-21, 23-26
RxP,
RxN
Signal Termination. Connect to SCSI bus signal lines.
6, 22
HS GND
Heat Sink Ground. Internally connected to the mounting pad. Should
be grounded.
13
ISO
Isolation. When pulled high, the DS2119M isolates its bus pins (RxP,
RxN) from the SCSI bus.
14
GND
Ground. Signal ground; 0.0 volts.
15
MSTR/SLV
Master/slave. Mode select for the non-controlling terminator. When
pulled high (MSTR), the DIFFSENSE driver is enabled.
16
DIFFSENSE
DIFFSENSE. Output to drive the SCSI bus DIFFSENS line.
17
DIFF_CAP
DIFFSENSE CAPACITOR. Connect a 0.1 F capacitor for
DIFFSENSE filter. Input to detect the type of device (differential or
single-ended) on the SCSI bus.
27, 28
TPWR
Termination Power. Connect to the SCSI TERMPWR line and
decouple with a 2.2 F capacitor.
