The MAX4589 is a low-voltage, dual 2-channel multiplexer designed for RF and video signal processing at frequencies up to 200MHz in 50Ω and 75Ω systems. It features low insertion loss, high off-isolation, low crosstalk, etc.
The MAX4589 is a low‑voltage, dual 2‑channel multiplexer designed for RF and video signal processing up to 200 MHz. It is offered in 20‑pin DIP, wide‑SO, and SSOP packages and is suited for applications such as RF switching, video signal routing, high‑speed data acquisition, and automatic test equipment.
The device operates from a single supply of +2.7 V to +12 V (or dual +2.7 V to +6 V) and features low insertion loss, high off‑isolation, and low crosstalk. Detailed electrical characteristics, timing diagrams for parallel and serial interfaces, and package dimensions are provided in the datasheet.
