PE4256 Datasheet Text
Product Description
The PE4256 is an UltraCMOS® Switch designed for CATV applications, covering a broad frequency range from 5 MHz up to 3 GHz. This single-supply SPDT switch integrates a two-pin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3volt supply. In a typical CATV application, the PE4256 provides for a cost effective and manufacturable solution when pared to mechanical relays.
