Unisonic Technologies L8020
L8020 is 4mA, and there is no remarkable change with load or logic state. The UTC L8020 can be used in applications, such as IF switch box, LNB switch boxes and twin LNBs, replacing many discrete components to save both manufacturing cost and PCB size as well as improving reliability. In this block diagram, the UTC L8020 provides the two polarity switches required to decode the two independent receiver feeds.| Part No. | L8020 |

DESCRIPTION
The UTC L8020 dual polarisation switch controller is one of a wide range of satellite receiver LNB support circuits. Its features include completely independent channels, and every channel provides two logic outputs under the voltage sensitive input. The two inputs of the UTC L8020 have a nominal threshold of 14.5V. Their threshold is temperature compensated to minimize drift. In order to achieve the transient protection by adding only a single resistor per channel, each input has a low and stable input current. Normal and inverted outputs are provided for each input. All outputs can source 15mA and sink 10mA making them suitable to drive TTL and CMOS logic, pin diodes and for IF-amp supply switching. The UTC L8020 works in a single supply ranging from 5V to12V. The quiescent current of the UTC In order to adapt the variation of environmental conditions, the ambient operating temperature is -40°C~+85°C.●
