Transient Voltage Suppressor
The provides LOW CAPACITANCE LOW LEAKAGE for two lines in common mode or two differential line pairs. Low capacitance 5 pF per line pair and the LOW STANDBY CURRENT provides a more stable signal in higher frequency applications and at lower operating voltages of 2.8 volts. The SLVU2.8K-4 bidirectional array is designed for use in applications where protection is required at the board level from voltage transients caused by electrostatic discharge ESD as defined by IEC 61000-4-2, electrical fast transients EFT per IEC 61000-4-4 and effects of secondary lighting. These arrays are used to protect two differential line pairs in a bi-directional mode by connecting both pins 1 and 8 to line 1 of pair one and 2 and u7 to line 2 of pair one. For protecting second pair connect pins 3 and 6 to line 1 and pins 4 and 5 to line 2 of the second pair as shown in Figure 2. The array can also be used for protecting two direct lines in the common mode by connecting either side of the pair to ground and the other side to line as shown in Figure 1.
