ESD observe handling precantions . Overtime soldering may cause Permanent damage 2 . The high level of TTL control signal should be higher than 3 . 5V and 2～3mA to provide 3 . When higher operating frequency and isolation and required , isolation measures should be used between input and output ports to abtain the guaranteed performance 4 . The decoupling capacitors (> 0 . 1uF and 10000pF ) are required to filter the iterference on the power port Switching Time 100nS/DIV TTL signal Output ● TEL:+86-311-87091891 87091887 ● FAX:+86-311-87091282 ● http://www.cn-bowei.com ● E-mail:[email protected] 45
