DS2119M

To maintain the specified regulation, a 4.7µF capacitor is required between the VREF pin (VREF) and

ground of each DS2119M. A high frequency cap (0.1µF ceramic recommended) can also be placed on the

VREF pin in applications that use fast rise/fall time drivers. A typical SCSI bus configuration is shown in

Figure 2.

DIFFSENS Noise Filtering: The DS2119M incorporates a digital filter to remove high-frequency

transients on the DIFFSENS control line, thereby eliminating erroneous switching between

modes. This filter eliminates the need for the external capacitor and resistor, which heretofore

performed this function.

NOTES:

1) DIFFSENS. Refers to the SCSI bus signal.

2) DIFFSENSE. Refers to the Dallas Semiconductor pin name and internal circuitry relating the

DIFFSENS driver.
