(90 ? balanced) to minimize trans- mission line reflections. in addition, these parts provide a very high level of pro- tection for sensitive electronic components that may be subjected to electrostatic discharge (esd). the input and output pins are designed and characterized to dis- sipate esd strikes of 15kv safely, a level well beyond the maximum requirements of the iec 61000-4-2 inter- national standard. using the mil-std-883d (method 3015) specification for human body model (hbm) esd, all pins are pro- tected for contact discharges to greater than 30kv. vcc r1 gnd in1 out 1 out 2 in2 1 2 3 c1 c1 r1 r2 6 5 4 d1_c v 3.3 d2_c gnd d1_i d2_i electrical schematic
