MAX4545EAP

四核/双通道，低电压，双向RF /视频开关 Quad/Dual, Low-Voltage, Bidirectional RF/Video Switches

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.
