General Description
●The MAX4545/MAX4546/MAX4547 are low-voltage T-switches designed for switching RF and video signals from DC to 300MHz in 50Ω and 75Ω systems. The MAX4545 contains four normally open single-pole/singlethrow (SPST) switches. The MAX4546 contains two dual SPST switches (one normally open, one normally closed.) The MAX4547 contains two single-pole/double-throw (SPDT) switches.
