DEVICE DESCRIPTION
The ZLNB101 dual polarisation switch controller is one of a wide range of satellite receiver LNB support circuits. It features two completely independent channels, each providing two logic outputs under the control of a voltage sensitive input. It is intended for use in Twin LNB designs, replacing many dIscrete components to save both manufacturing cost and PCB size whilst improving reliability.

FEATURES
• provides polarity detection and control
• transient resistant
• low input current
• low supply current
• temperature compensated input threshold
• standard and inverted output available simultaneously wide supply operating range
• dual polarisation switch
• eliminates external components
• simplifies design
