Datasheet

MAX4529
Low-Voltage, Bidirectional
RF/Video Switch
______________________________________________________________________________________ 11
MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT IC TERMINALS.
OFF ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NC TERMINAL.
ON LOSS IS MEASURED BETWEEN COM_ AND "ON" NC TERMINAL.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
