DS3890

The DS3890 is advanced IEEE-896 future bus compatible devices designed specifically to overcome problems associated with driving densely populated backplanes. The features of DS3890 can be summarized as (2)driver output capacitance less than 5 pF; (3)1 volt bus signal reduces power consumption; (4)trapezoidal driver waveform reduces noise coupling to adjacent lines; (5)precise reciver threshold track the bus logic high level to maximize noise immunity in both logic high ahd low state; (6)open collector driver output allows wire-or connection.

The absolute maximum ratings of the DS3890 are: (1)supply voltage: 6V; (2)control input voltage: 5.5V; (3)driver input and driver output: 5.5V; (4)receiver input and driver output: 5.5V; (5)storage temperature range: -65 to +165; (6)lead temperature: 260.

The following is about the electrical characteristics of DS3890: (1)VIH: 2.0V min; (2)VIL: 0.8V max; (3)IIL An: -1mA typical and -1.6mA max at VCC=max, VIN=0.4V; (4)IIL Dis: -180A typical and -400A max at VCC=max, VIN=0.4V; (5)IIH: 40A max at VCC=max, VIN=2.4V; (6)II: 1mA max at VCC=max, VIN=5.25V; (7)VCL: -0.9V typical and -1.5V max at VCC=min, IIN=-12mA; (8)VOL: 0.75V min, 1.0V typical and 1.2V max at VCC=min, RL=18.5; (9)IOH: -20A min and 100A max at VCC=max, VOUT=2V.
